Over 2 percent of the US’s electricity generation now goes to bitcoin::US government tracking the energy implications of booming bitcoin mining in US.
What a huge waste in times where we have global warming and urgently need to cut our carbon footprint a bunch of greedy people are living like there is no tomorrow.
There is no tomorrow, because of global warming.

Yes, good, blame the poor, make them feel responsible. Forget corporations, forget who is actually burning the earth down. The earth is going to die because YOU drove a gas car, used bitcoin, and don’t like paper straws.
Bitcoin mining is a multi-billion-dollar business. The block reward along is 900 BTC = 38.7 million USD a day (at 43,000 USD per BTC as of writing), shared between half a dozen big mining pools. Bitcoin mining equipment costs thousands of dollars.
Mining bitcoin is solely a game for men with means.
Lol, $40 million USD. The actually rich people, the people standing up there laughing at all of us, are moving $40m themselves as pocket change. Zuckerberg just got $700M. They blocked Elon from getting $56000M. The 1% are laughing at the 99% and I’m starting to as well.
40 million USD per day. That’s 14 billion USD annually.
Also I’d like to point out that it’s not 1% of the population that’s like that, more like 0.01% or even just dozens. There are many rich people, but few are crazy rich like that.

Ah yes, the poor who dig Bitcoin. Sorry but if you are having money to dig Bitcoin you aren’t exactly poor. And you know if we all as humanity change just our diet, the effect would be immense, so it is not only the corporation’s responsibility but also the collective.
Oh hey, it’s the guy Dan Olsen was talking about in that Folding Ideas video!
The economics of Bitcoin mining are a bit weird in that it impossible to make it more energy efficient.
The system auto adjusts the computational complexity of mining bitcoin so that it always costs a little less than one bitcoin to mine a bitcoin, and at scale the only variable expense is electricity so as the price of bitcoin goes up, so does the amount of money that must be spent on electricity.
Current 6.25 Bitcoin are mined every 10 minutes. So globally about $2 million must be spent on electricity every hour.
In a little over 2 months the block reward cuts in half to only 3.125 bitcoin every 10 minutes. That will have the side effect of reducing the money spent on electricity for mining bitcoin so long as the price of bitcoin remains the same.
“The System” is not really that intelligent. The statement that “It will always cost a little less than one Bitcoin to mine a Bitcoin” is only correct because the incentives in the system steer everyone toward that. There’s no direct link between the two. Bitcoin Miners are intently aware of how much energy they consume, and if the price of Bitcoin dips below what they are paying for electricity, they likely will shut down their rigs, because no one wants to mine at a loss.
The real issue with Bitcoin is that the algorithm used to find more Bitcoins is kind of basic in terms of its difficulty mechanism. It was the first one ever used for cryptocurrency. It was originally envisioned that owners could mine more bitcoin with spare cycles on their CPU, but since it was first designed, people have come up with custom mining chips that can mine faster and much more power efficiently. But paradoxically, this has made things worse, because the bitcoin mining difficulty simply scaled up to account for all that. So now the only way to mine Bitcoin is to have this custom hardware – it’s too hard to do any other way – and you need so much of it that you are just as power hungry as before.
There are other algorithms that don’t have these same problems. They have been designed to use other computing resources (like gobs of memory) that are much harder to concentrate on custom chips, making it much more expensive (monetarily and spatially as well as computationally) to simply spam more of them. Ethereum uses a totally different model now that doesn’t rely directly on power consumption at all.
OG Bitcoiners seem to think that the massive power consumption is a net benefit, because it is spent in making the overall network more secure, and less likely to be attacked. So they will never try to change their block algorithm, even though other projects are just as secure with less power consumed. And if that opinion holds, the only way to eliminate this source of power consumption would be to crash the price, and cause the Bitcoin miners to have to mine at a huge loss to continue.
Instead of using an independent RNG to determine the next block producer Bitcoin miners are essentially flipping coins and whoever manages to flip like 78 tails in a row gets to create the next block. How crazy is that?
What’s even more astonishing is that when someone creates a new Crypto wallet, it creates an obscenely long random number as a seed, and just starts using it. As long as the number is sufficiently random, the chance that someone else has generated the same random number is so small as to be functionally zero. So you don’t have to ask for anyone’s permission first before using Crypto. You only have to ask the Universe for some of its entropy, and off you go.
It’s the same math of large numbers that leads us to conclude that every time we shuffle a deck of cards, the result is a deck that nobody in the history of the Universe has ever seen before. 52! is an insanely large number, which is on the order of 10^67 .
https://quantumbase.com/how-unique-is-a-random-shuffle/
The math behind Crypto is sound, and ensures that everyone’s wallets stay secure. Noone but their owners can move funds out of their wallets, and once a transaction is sufficiently confirmed, it can’t be undone. The only real threat to this is Quantum Computing, which might be used someday to Crack the relationship between public and private keys which is unassailable now. We’ll see whether the people who run these Crypto networks are able to change their algorithms to be Quantum resistant in rhe future.
Oh yeah, Quantum computing won’t ruin crypto. Cardano already has plans to transition to quantum resistant crypto primitives. We just need to wait for some standards to form around which algorithms should be used in the future instead of current ones. I’m not worried about quantum computers at all.
Oh, I have confidence that we can develop quantum-resistant crypto. My concern is in the governance of all the projects. Cardano seems to be in good shape, but it put some thought into how to make decisions that have at least some community involvement. But the market is driven by BTC mainly, and they have some issues in how they run themselves.
BTC’s protocol has gotten steady, incremental improvements for 15 years without a single hour of downtime. Lightning was deployed a few years ago and continues to grow each year and get easier to use and deploy. Migration to quantum-resistant algorithms is in the interest of all parties who use the system including miners, banks, hedge funds, developers, users, etc. It’s a very easy problem compared to other questions they faced around blocksize, taproot, etc.

Quantum computing is not a threat at all tbh. Computers that can crack public key encryption are “20 years away” and require some fundemental shifts in our ability to control physics. And that’s the lab production version, not one available on the open market.
Quantum-resistant algorithms already exist and continue to be refined. Things will get migrated long before they become a realistic threat.
the massive power consumption is a net benefit, because it is spent in making the overall network more secure
I really have trouble understanding this argument. Joining a mining pool secures nothing.
The whole point of mining is to arrange transactions into blocks, and then generate a cryptographic hash of the block that meets some difficulty criteria. It costs some small amount of computing to do that. But an astonishingly large number of hashes won’t meet that difficulty criteria, which is why miners have to try a gazillion times to find one that works.
However, once a block has a valid hash, it is added to the chain. Then, the hash of that valid block must be used in the next block, which will be equally hard to find.
By “security”, what is really meant is “How can I be sure that a transaction can’t be undone once it is committed”? And it’s because all these blocks are stacked on top of each other, and cryptographically related. Once a transaction appears in a block, and a few blocks get mined on top of it, it becomes prohibitively difficult to un-do it, because someone would have to put in the computing power to re-authenticate a string of blocks, all while the rest of the network is adding blocks to the valid chain at a faster rate.
The security of this whole arrangement has so far been working good as well.
In order for someone to try and perform a 51% attack, they’ll need to either compromise a large swathe of existing miners (e.g if the government seized control) or create/acquire hardware totaling more than 100% of the existing network today plus growth while you attempt to build more than 100% and then maintain growth over the rest of the network.
As the network grows that becomes exceedingly more difficult to perform.
I have really high hopes for something like proof of
workstake, but it’s not without it’s own problems either, and with Ethereum, it’s the first massive scale test, so it’s not as battle tested as proof of work yet, although it’s been used in smaller projects so there has been some testing. With more money on the line though, comes more will to try and break it, or use an exploit you may have held back beforehand.One interesting difference with POW/POS is that if a miner/entity does somehow perform an attack, they keep the hardware and can continue to try. With POS, they should get slashed in which case the money is gone. But with POW you have the barrier of actually acquiring the correct amount of hardware, meanwhile in POS, you just need the money so there’s no manufacturing/lead time and will be easier to achieve by state actors.
Bitcoin has literally 2 pools who have more then half of the block production. Also not all PoS systems have locking and slashing btw.
Pools that people could leave if something suspicious was happening.
Very different than an individual entity.
Well… Cardano has like 30 different pools that add up to 50+% of the block production.
If something sus was happening with one or more of those - people can just leave them.
Same thing but 30 is better than 2.
My main issue with Bitcoin isn’t even the POW vs POS angle, it’s the fact that the core devs see no problem with their current POW algorithm, which is not designed to put any bounds at all on energy consumption. But I also think they should have increased the block size, and you can see where that discussion went.
I sometimes have a weird vibe like someone somehow crippled Bitcoin by making it not able to evolve and develop. I mean… If I wanted it gone and couldn’t just destroy it, I would cripple it. Idk, just feels sus.
Anything that makes bitcoin more valuable is a financial benefit to all people holding bitcoin. Anyone who has a brilliant idea is financially better off by making their own coin.
Miners, who have money tied up in bitcoin-specific hardware, have a vested interest in maintaining the POW system or else their capital loses value.
There are probably exchanges short on bitcoin that stand to profit from a decreasing price.
So yeah. Someone crippled bitcoin. That someone is Satoshi.
Fuck the core devs is really all i have to add to that without going into it…
Luckily things like Ethereum and others were born due to them.
I have really high hopes for something like proof of work
I just realized I wrote the above, but if it wasn’t clear, I meant proof of stake.
the power reqs keep the plebes out.
I remain convinced that crypto is just tech bros trying to redo the early days of the stock market so they end up rich instead
not a bad assessment.
I think what needs to be considered here is what we consider a waste of electricity. Efficiency calculations are dependent on waste, So I personally think electric cars are a waste of resources, they consume electricity to run and consume non renewable resources to produce just to move a maximum of 1-5* people per journey. Whereas an electric which still uses this resources can move over 10x that amount per journey, and trains over 30x that amount per journey.
So to me that’s energy inefficiency at the consumer point.
Now let’s look at energy generation and transfer. At the moment, alot of energy production is a for profit business, Company A builds a solar farm, Company B builds a Coal power plant and Company C (This would be overseen by the government, not a private company) builds a nuclear reactor. All 3 of these companies produce various amounts of electricity with different efficiencies, but all must be sold at the same price. It might only cost £0.01/KwH on the solar farm to produce, but must be sold for £0.33/KwH, the coal would be £0.27/KwH and nuclear would be £0.45/KwH.
You have 3 generation methods, each with strengths and weaknesses all being forced to sell for the same price. Normally in a capitalist system you see “Competition” (not really) on the market. Company A would say “We’re cheap, but can only guarantee 97% uptime due XYZ issues”, most homes would be fine with me this. Company B + C “We’re not as cheap but we can offer 99.9% uptime” This looks great for companies needing that security in uptime.
I’ve gone on a tangent and can’t be bothered finishing this post maybe someone else will.
Is it not a way in which some governments could collaborate to end this Bitcoin madness?
Genuinely question.
Like maybe some big countries could agree to collaborate and join resources to make a 51% attack and bring Bitcoin price to 0 so people stop wasting resources on it.
2% of enery usage for something that do not add any value to society is INSANE.
I think the best solution would be to properly tax carbon. That way Bitcoin miners would either become unprofitable or move to greener energy.
I don’t think it’s a good idea to establish the precedent that gov’t can decide what you can and cannot do with your energy. You may think it’s a waste of energy, but if the externality is properly taxed, I don’t see the problem with letting it continue
Agreed, tax what the problem is not just one facet of it.
I think the best solution would be to properly tax carbon. That way Bitcoin miners would either become unprofitable or move to greener energy.
I think cap and trade can be a good idea, the problem is getting all the countries in the world to sign onto it. Any country that doesn’t ends up with a competitive advantage. But if you somehow got them to all agree, blockchain actually provides a perfect way to build a cap-and-trade system that every country can participate in, transparently, without having to trust one country or group of countries to run it honestly. That’s the essential problem blockchain solves: administering systems trustlessly.
Bitcoin miners do by and large use green energy since it tends to be the cheapest (off-peak hours from over-provisioned grids). If electricity gets more expensive, it doesn’t mean it becomes unprofitable to mine, that’s only one side of the equation. The other side is how much people are willing to pay to get transactions added to the blockchain, which is a number, on average, that has increased year after year. Not that you ever need to make an on-chain transaction, with Bitcoin lightning you can do transactions off-chain while getting much of the security of on-chain transactions. You can move money internationally in under a second for pennies in fees. And it works just as easily as venmo. In fact, if you have cash app on your phone, you already have the ability to use the lightning network, though it’s a custodial wallet (meaning you are trusting cash app not to take/lose your BTC).
Then it’s just gonna suck up “green energy”. It’s still energy. We have already have provably secure PoS (not Ethereum btw, it’s PoS sucks ass).
Yeah I’m pro PoS in general, but I don’t think we should forbid people from running PoW on their own computers. Seems like a step too far.
Side note, what’s wrong with Ethereum’s PoS in your opinion?
Oh yeah, I was never for banning PoW. I just don’t like it since I know same or better can be achieved with a well designed PoS.
Ethereum PoS has slashing so people are scared to stake thus causing low participation rate. Also, in Ethereum, you need a minimum amount of 32 ETH to solo stake. Ethereum also doesn’t have a native liquid staking and has locking, unlike Cardano. And you can’t delegate your coins without giving up custody of them. Cardano PoS is designed completely differently and is natively liquid with no locking, no min amount to stake, native delegation and both delegation and self-staking is risk free when it comes to your balance. Worst case - you miss out on those 3.5% rewards for the period your balance is delegated to a pool that’s not doing its job. All of this is the reason staking participation is like 65% in Cardano. Would probably be even higher if it wasn’t for lost coins and large whale wallets that are not staking/delegating for some reason.
I think the 32 ETH lockup + slashing does make it riskier to stake, but it also makes the chain more secure. As a malicious Ethereum staker, every failed attack costs me a lot of money. As a Cardano staker, I can attempt an attack many times because there I don’t lost that much if it fails.
The lack of liquid staking is the only real drawback I see here, as it has allowed some centralization in the Lido token. Ethereum has yet to address that issue
Yeah, but people are just gonna leave your pool if you try to attack the network or miss blocks. (And good luck attacking the network where even the largest 2 entities Binance and Coinbase together only have about12% of block production (stake)).
Like… ye, it’s not happening.
And why would you attack a network (if you could) where your value is stored. It’s a suicide.
If you did have so much stake, it might be smarter to play by the rules.
If you destroy Bitcoin, another currency would take its place.
Good. Most don’t use proof of work anymore because they don’t feel the need to watch the world burn for no reason other than propping up techno bros.
A lot still do, and that’s where the miners would go
If governments started regulating bitcoin because it was proof of work based then people aren’t going to pump real money into another proof of work scheme to replace it - why would they take the risk of it happening again when there are alternatives? the mining profit margins would disappear and so would they.
It woulf take years and years to pass such a ban in a significant number of countries - assuming they would ever want to cooperate on this, that is
Oh I think that’s probably true, but the question assumed it taking place

Some have tried, they have all failed. Bitcoin is international. A 51% attack is so implausibly expensive that nobody really has the resources to pull it off. Even if you had enough money and energy to burn, there is the small problem of acquiring enough of the specialized hardware to do it (ASIC miners), and potentially the specs and fab to make that hardware. People will see it coming a mile away. Don’t want to use ASICs? Enjoy at least a 100x increase in energy and equipment costs. And it gets more expensive every year. If you had that much money to put into destroying Bitcoin, it would be much better spent on an ad campaign telling people Bitcoin was bad than doing a 51% attack.
A 51% attack doesn’t prove Bitcoin is broken, it proves the protocol is working exactly as expected. A 51% attack causes a temporary fork. This happens all the time organically when two miners find the next block at the same time, it’s a natural part of the protocol. That’s why for really large or important transactions on main chain, you wait a few blocks before considering them fully secured.
Bitcoin’s value to society is the ability to easily transfer money from point A to B and having a clear fiscal policy it has kept to for 15 years, 365 days a year, 24/7 without a single hour of downtime, a bank holiday, or getting hacked. There’s a reason big money like hedge funds and private banking are investing in it: it’s actually useful and has massive potential. The market cap of Bitcoin is 850 BILLION USD, that’s bigger than the GDP of Sweden or Israel or Vietnam. People use it to move over a trillion dollars of value a year. You can debate how much of that movement is trading & speculation vs use as a currency, but it’s a trillion nonetheless. I personally pay for things regularly with Bitcoin, you’d be surprised how many places you can spend it when you start looking. And it’s available to anybody with a cellphone and halfway reliable internet access, including the billions of people who are “unbanked” and lack access to stable banking infrastructure.
Transactions on Bitcoin lightning occur in under a second and cost pennies in fees. That’s to send it across the room or across the globe. Remittance services and bank wires use just as much energy and cost 10x-1000x as much. And they waste not just energy but human capital as well, we no longer need humans manually sending bank wires like it’s 1910. You just don’t see headlines about the energy impact of bank wires or western union because it’s not novel, we just accept it as a cost of our financial system.
That’s not even getting into the secondary costs to the environment of running a society on an economy based on an inflationary currency which requires that currency be rapidly spent because it’s getting constantly devalued. That’s a great strategy to rapidly industrialize the world, but it’s not a great strategy on a globe with limited resources. Tell me, if you knew your dollar would be worth 10% more next year, would you be more hesitant to spend it? Might you consume less if you knew saving money in your bank account would actually cause it’s value to stay the same or increase over time? Might you focus your spending more on quality products that will last instead of just buying the cheapest thing because if it breaks, you can just buy a new one? This isn’t just on a personal level, this same kind of calculus is used by big investment firms to build everything that won’t last. Buildings, stadiums, entire cities, financed with money that is constantly losing value. Bitcoin’s value relative to goods and services will fluctuate like any currency does, but the supply of the currency does not increase. There are 21 million which will ever be minted. Your 0.1BTC will always be 0.1BTC and will always represent 0.1/128M% of the total supply. If the Bitcoin economy grows, you share in that growth and the value it produces instead of seeing the difference printed away and given to whoever controls the money supply and whoever they want to give it to.
Skip ad. Bitcoin is pumped through ridiculous leverage and printing of “stable” coins like tether. The scam hasn’t unraveled yet, but that doesn’t mean it won’t.
Do you know that Tether and Bitcoin are different things? Because it seems like you don’t.
Do you know that tether is printed and used to buy bitcoin? Because it seems like you don’t.
Stablecoins are a house of cards built around stably relating to another house of cards which is the entire inflationary fiat system. Every single asset and currency is speculated on via the open market. Bitcoin is no exception. If it is overvalued or undervalued, that creates market opportunities for people to exploit the difference. The market has decided it’s worth a certain amount today, it will be another amount tomorrow. Not unique to Bitcoin. Every year people have said Bitcoin was “overvalued” and powered purely by hype, on average, the market has decided they were wrong the following year.
Any honestly-run stablecoin inherently has to collateralize their coin with something. They can buy BTC (and do), they can buy USD (and do), they can buy wheat futures (but I’m not sure they do). Ultimately, a diverse portfolio would probably be wisest. Yet you don’t see anybody complaining that “USD is being pumped by Tether/USDC”. Why? Because it’s not a problem.
??? How is USD being pumped by USDT/USDC? I’m lost, lol.
The previous poster is alleging BTC is being “pumped” by tether because tether is collateralizing their coin by buying BTC. I’m pointing out that they also buy USD yet nobody is complaining that USD is being pumped.
If you buy a stablecoin, the hope is that the stablecoin is tied to an actual dollar (or whatever it is supposed to represent). This means if you buy $1 in tether, tether should buy $1 USD on the open market, put it in a vault, and wait until somebody else comes back to sell that dollar back to Tether. But you can buy other stuff too, other assets, which when you start managing large amounts of money is important for risk management. Plus they can make some returns that way. Some stablecoins pass the returns on to people who hold the stablecoin. Generally, these stablecoins are collapses waiting to happen for these and many other reasons.
People defending Binance and Tether are either:
- Clueless and haven’t done any research
- Brainwashed
- Part of the Binance/Tether cartel
- Paid to do it
- Lying to themselves
- Aware of the truth, but want their bags to continue to be propped up by fraudsters
Which one are you?
IDGAF about Tether, IMO it will collapse one day, and the world will be better for it. It’s a currency whose basis is “trust me bro”.
I just wish it collapsed sooner. At this point the effect on the whole crypto sector, be it BTC, ETH or ADA will be unimaginable for most people.
Please don’t buy Bitcoin if you want the Earth to last.
I avoid it to not feel like a dumbass.

Nice dislikes. Can you point to even one factually incorrect thing I said?
“will transition to decentralized”, “most likely”, because we can always trust people to give up their vast power and wealth voluntarily right?
Or you could use Bitcoin. Which has been decentralized and reliable for 15 years and doesn’t suffer from inevitably increasing centralization like every proof-of-stake coin does. And doesn’t have massive requirements to run a full node/validator, which inherently increases centralization. Scaling crypto requires adding layers on top of the base layer, not making the base layer so huge you need a server farm to run a full node. Lightning scaled Bitcoin to essentially an infinite number of transactions per second without increasing the chain size.

The whole idea behind IOG is to build the Cardano to the point it can become an independent, self-sustaining and self-developing thing.
So weird how proof-of-work currencies like Bitcoin were able to do that without making a centralized governance structure which promised to hand over the keys later.
yes TWO mining pools control more than half of the Bitcoins block production
Mining pools have been getting more distributed the last few years thanks to some network upgrades. Pools relay the results of mining, they don’t do the actual mining, they have no hashpower. In the past, pools have tried to censor transactions, and seen their pool get abandoned by the entire network. They couldn’t censor them of course, they could only temporarily delay them. Pools have no power. They can’t double-spend or 51% attack because nearly all of the BTC they acquire flows right back to miners. They can’t afford the cost of a 51% attack more than any other entity or nation-state. They can’t spend money which isn’t theirs, even if they could do a 51% attack. If you look at hashpower instead of pools, you will see it’s much more decentralized.
Actually, in Cardano, the rich don’t really get richer because every single holder no matter how small gets rewards proportional to their holdings (if they stake or delegate, which is risk free and no locking unlike Ethereum and Solana garbage PoS).
The rewards proportion isn’t why the “rich get richer”. The rich get richer because coins in transit can’t stake. This means the only coins that can stake are existing coins, sitting in wallets, doing nothing but staking. You are printing an inflationary currency supply, making new coins, and giving those coins to those who are already sitting on the most coins. The more coins you have, the greater portion of your coins will be sitting instead of moving, because why not, it’s free money right? For doing nothing. It’s why supply inflation/currency devaluation hurts the middle class more than anybody else. They have an emergency fund, they have a savings account, they are saving up for a down payment. They have more cash on hand than rich people or poor people. Rich people have assets. Poor people don’t have enough money to be effected. The proportionality doesn’t matter here. What matters is the direction of the new coin flow: towards those who are already sitting on coins.
In a fixed supply, your coins may gain value over time due to deflationary pressure. Every coin is effected the same way. In cardano and other inflationary currencies, you’ve added an additional layer where you are printing coins and handing them to those with the most coins already. Not only does this give them more coins, it reduces the value of the coins held by people whose coins recently transited.

Correct me if I’m wrong, but don’t the pools send the block that needs to get mined to it’s participants? If that’s the case, imagine if those 2 top pools decide to do sus stuff or if they get compromized by malware. This could create some trouble until miners migrate. Again, correct me if I’m wrong. Having 2 such large mining pools is not cool and there is no hiding from that fact.
I’ve love to see more pools, but I just don’t think its as big of an issue as it’s often made out to be, since they don’t actually control the hashpower. The blocks they send to participants are immediately verifiable as real or not, miners don’t have to take a pool’s word for it and will often have full nodes monitoring the blockchain to make sure any given pool doesn’t go over 51% hashpower.
Pools really can’t do sus stuff. There are a few things pools could do or try to do:
-
Censor transactions by refusing to include them in blocks. They are financially incentivized not to do this, since not including a tx in the block means selecting the next least valuable tx in terms of fees. The immediate damage from this is basically nil, the next block will probably be made by a different pool and the tx will go through. So transactions can’t get censored, only delayed. But people will notice, and that pool will lose all its hashpower and its means of making money, which is exactly what happened when this scenario happened before. Bitcoin has faced, and beaten back, this exact attack before.
-
Conspire to perform a 51% attack. They don’t just need 51% between each other, they need enough hashpower to roll back previous blocks, which means maintaining 51% for several blocks in a row. One of the primary reasons 51% attacks are not viable is that you need to give that Bitcoin to somebody, get something of value in return, and then un-spend it. They need to transfer you that equivalent amount of value before it gets unspent. Nobody transferring hundreds of millions or billions of dollars worth of value is going to be happy with a one block confirmation. Or even a three block confirmation. Even if they were, what items can you actually transfer that quickly? It’s just not viable as an attack method, there is no money to be gained. Pool operators are fallible at the rest of us, if there was a viable way to do a 51% attack, somebody would have done it by now. But it’s not.
What do you mean, coins in transit can’t stake? I have 10 coins (wallet staked), you have 0 coins (wallet staked), I send you 5 coins (atomic operation)
If a block moves a coin from a to b, that coin can’t also the coin that stakes that block. Granted, I am showing some ignorance of Cardano here, but that’s how other PoS systems work. And there is usually a “cooldown” of a couple blocks to prevent that coin from staking for a while for security reasons.
I didn’t know about cardano’s capped supply, you’ve taught me a few things in this thread. Until the system is actually decentralized and the cardano devs give away the master keys and let the network truly run on its own, I have little interest in it. And based on some cursory reading, centralization of relays and growing chain size are much more of a concern than with Bitcoin. Best of luck to you.

Can I know why so many people disliked this? Did I said something that is not factually correct?
PoS inevitably leads to centralization and requires an inflationary currency supply. That is the problem. Coins in transit can’t stake. Which means the only coins that can stake are coins that already exist and are sitting on a staking node. You are paying those stakers with an inflationary supply. Which means you are minting new coins and handing them to users who already have the most coins. This leads to centralization of the supply over time, and therefore, control of network consensus. A few rich, powerful people end up controlling the whole system, just like our existing banking system. No thanks.
Most of those PoS chains also have massive chain sizes/system requirements compared to Bitcoin, which means they can’t be or remain nearly as decentralized, neutral, and secure.

Honestly eth just made more progress between built in smart contracts and proof of stake, I’m surprised Bitcoin is still holding on. Sunk cost fallacy I guess.
I’m not an economist or anything, but I don’t think it’s a sunk cost fallacy I think it’s just a market. They’re all mining both. Just leaning heavier on whichever one makes them more money in the moment. The market is going to have a hell of a lot of inertia.
The market is run by people, and people have been proven not to be rational. So, sunk cost easily applies to the market
Come on, that’s logic 101
All a are b
some b are c
all a are not c.
You can’t even claim that most A are C with that logic
I can’t quite follow you beyond the fact that in your example “all A are not C” is correct
Yeah I think that’s our major problem here.
That’s a good point a lot of the crypto markets influence is still more focused as an investment vehicle for getting more fiat wealth, that’s more reasonable to me. I guess I am just a die hard engineer and the practical uses matters a lot more than the price of tulips.
I mean honestly you’re right. Nobody should be left on the Bitcoin side from an environmental or a cost standpoint. But I have no idea how long it’s going to take to catch up.
I will say that at some point if there is an awakening, bitcoin’s going to crash so f****** hard. And the first ones out are going to make all the money.

PoS and PoW both suffer from a centralizing of power issue IMHO so that doesn’t sound implausible, TruthLabs seems to be throwing a lot of allegations towards the network though but I am not seeing the evidence yet.
Did you only skim through? They are literally presenting hard on-chain facts.
Honestly just couldn’t find them just second hand outlets saying they say.
Yeah, it still seems like a lot of unfounded claims, like they point to an account and say “this is the CCP” and it very well be but I keep failing to see where those claims are substantiated.
If you dig some deeper you will see it is. Ethereum Prometheum Wanxiang CCP
Yep, Ethereum uses less power than a debit/credit transaction or even a PayPal transaction.
Have you read some of the work Visa has been doing with EVM and zero knowledge roll ups? Pretty interesting stuff.
Fucking nightmare.
I wish all my the nightmares would be like this!
At first I thought the article was inaccurate but It sounds like there has been a huge increase in US Bitcoin mining since 2020.
Some interesting information from their source article:
“The CBECI estimates that the global share of Bitcoin mining occurring in the United States rose from 3.4% in January 2020 to 37.8% in January 2022”
“the CBECI estimates put electricity supporting Bitcoin mining in 2023 at about 0.2% to 0.9% of global demand for electricity.”
Who knew that fake money could do so much damage?
Tons of people. Tons of people did.
This is the best summary I could come up with:
While its analysis is preliminary, the Energy Information Agency (EIA) estimates that large-scale cryptocurrency operations are now consuming over 2 percent of the US’s electricity.
The EIA report notes that, in the wake of a crackdown on cryptocurrency in China, a lot of that movement has involved relocation to the US, where keeping electricity prices low has generally been a policy priority.
One independent estimate made by the Cambridge Centre for Alternative Finance had the US as the home of just over 3 percent of the global bitcoin mining at the start of 2020.
Tracking the history of five of these plants showed that generation had fallen steadily from 2015 to 2020, reaching a low where they collectively produced just half a Terawatt-hour.
To better understand the implications of this major new drain on the US electric grid, the EIA will be performing monthly analyses of bitcoin operations during the first half of 2024.
But based on these initial numbers, it’s clear that the relocation of so many mining operations to the US will significantly hinder efforts to bring the US’s electric grid to carbon neutrality.
The original article contains 783 words, the summary contains 186 words. Saved 76%. I’m a bot and I’m open source!
Honestly surprised it is that low.
I can’t believe its that high, what a fucking big, stupid, dumbdumb thing. So wasteful and for what benefit?
The argument on the other side of the coin is that renewable electricity is often produced in excess, and when it cannot be stored, mining bitcoin is an effective way to convert that excess electricity into money. Normally, that energy would just be wasted, reducing the efficiency and economic viability of renewable electricity sources.
This argument is sound, but the problem is that it doesn’t describe reality. The reality is that Bitcoin miners set up shop wherever electricity is the cheapest and consume inordinate amounts of electricity whether that electricity is in excess or not, and whether that electricity was generated renewably or not.
First of all I doubt the profits generated from this go towards anything or anyone worthwhile, second, doesn’t bitcoin mining cause diminishing returns individually and across the network? Like aren’t the problems getting harder and more expensive computationally?
The mining difficulty adjusts automatically so that 1 block is produced every 10 minutes on average.
More miners join, more difficult and expensive it gets, to the point it forces the least efficient miners to be turned off, or seek cheaper electricity. If too many leave or the price of BTC raises, more people are incentivized to join.

So wealth continues to be concentrated by the wealthy while polluting a bunch.

You know the business is legit, when the only complaint is “BuT ThE RiCh!!”
The cops used to find people growing marijuana in winter by the snow thawed on the roofs. Now there would be a mining rig under such a roof (also, most of the time there will be no snow, and then too much snow on occasion)
Benefit is a better world.
Maybe the larger American owned projects are located in places where energy is cheaper / cooling is easier
2% for the reliable independent monetary system seems like a good deal. How much does our current one consume with all its flaws?
Bitcoin is anything but reliable and independent. And it’s 2% for the miniscule inconsequential amount of transactions it does compared to the amount of transactions happening.
More like 2% for a casino.
Bitcoin is a SnitchCoin. Every detail of every person on every transaction is broadcast to anyone and everyone listening. All the way down to IP address.
Fantastic solution to force very gorramn business to conduct their bullshit in it and pay their fucking taxes.
Any REAL person can handle theirs in Monero and swap off Bisq for now until Monero has their own TOR Market.
How much goes to the dollar?
There’s a powered device or 5 in every store connected to a credit server.
All that energy for bitcoin only supports 7 tx/s. Digital dollar payments do tens if not hundres of thousands per second.
tx/s?
Transactions per second. Bitcoin is slow and expensive to get your transaction “approved”.
Expensive is relative. It’s expensive to send a $5 transaction and pay $1 in fees. However, you can move a million dollars in value and pay that same $1 in fees. That $1 in fees can also open a lightning channel which can contain essentially infinite transactions within it. For small transactions, Lightning transactions settle in under a second for fees measured in pennies.
Compared to a bank wire, western union, or other remittance services, $1 is an absolute steal.
Transactions per second
On main chain. Via lightning you can support all the capacity of Visa/Mastercard/banks and then some. Main chain provides the security for lightning, lightning provides the transaction storage space and infrastructure.
The lightning infrastructure, if you graph it, looks very similar to existing global payment networks. The difference is that transactions settle instantly because they are protected by the underlying blockchain and they are automated with no middlemen to delay things. No complicated currency conversions, no banks negotiating liquidity in blocks manually and having to buy/sell other assets to stay in balance, no bank holidays, less fees. Which means you can take your money from person-to-person faster, which reduces friction in the economy. Which is exactly what a good currency should be.
Are you paid to post that nonsense?
For those in blissful ignorance: This uses so-called channels between participants. Opening a lightning channel means, basically, putting bitcoin in “escrow” on the blockchain. This requires multiple transactions on the blockchain. Bitcoin doesn’t even have enough capacity to open a channel for each baby being born.
The amount that both sides put in “escrow” is the max payment imbalance that a channel can accept. Say, you want to use a channel to buy a car for $20k, then you need a channel that both you and the other guy have put in $20k in bitcoin.
If some calamity happens, these funds are lost in nirvana.
This requires multiple transactions on the blockchain
It literally requires one to open and one to close, so like $1 most of the time in fees. If you have a custodial wallet, it requires zero. You can keep a channel open forever. Within that channel, you can have essentially infinite transactions between you and any other party and you can use the channel to route payments to anybody on lightning network. All those transactions settle within a second and have fees measured in pennies. A channel doesn’t need to be opened for every baby being born, babies don’t use money. Seriously though, there are additional improvements coming down the pipe (like channel factories) which enable you to use one on-chain tx to make hundreds of channels. People do not understand the scale lightning works at.
The amount that both sides put in “escrow” is the max payment imbalance that a channel can accept
All of this is abstracted away for you as a user, you don’t have to worry about it, especially for custodial wallets. Most people earn and spend roughly the same amount each month, so liquidity isn’t anything they ever need to think about. There are also automated ways to rent inbound liquidity which are incredibly cheap, that can be done with self-custody wallets.
Say, you want to use a channel to buy a car for $20k, then you need a channel that both you and the other guy have put in $20k in bitcoin.
Wrong. If you want to buy a car for $20k, you have to put $20k into lightning. The other guy doesn’t have to put in anything aside from the $1 in on-chain tx fees to be on the lightning network in the first place, which he doesn’t even pay if he has a custodial wallet. Then you send that 20k to the guy with the car. Now you can receive up to 20k in payments in that channel. Not that you would spend $20k via lightning, if you are buying a car and moving that much money, use main chain.
If some calamity happens, these funds are lost in nirvana.
Calamity doesn’t happen, funds don’t get lost. Custodial wallets literally never encounter this, it’s all handled by your custodian. Non-custodial wallets also rarely encounter this, all the incentives are lined up to make “force closes” (which is what I assume you are referring to) rare. And of those force closes, the only risk is that your counterparty publishes an old version of the channel. You have like five days to correct and publish your more recent version to claim your funds. And if they tried to cheat you out of your funds, you get your funds and they pay a penalty. Given that watchtowers are basically automated, this never happens. Your funds from one of your channels might be stuck on-chain for a few days at worst, this is not a nightmare scenario. Banks and traditional payment processors have random holds all the time, especially when dealing with anything international. The difference is, the funds in lightning are always yours because you have the key. There is no scenario where when properly used, you lose funds in lightning.
I can see that you don’t know how this works. That’s ok. It’s nonsense. No one needs to know about that.
Custodial wallets work just like checking accounts, without the regulation. Crypto victims like to say: Not your keys, not your coins. The custodian owes you the crypto that you have in your account/custodial wallet. You own a debt payable in crypto. If the custodian goes bankrupt and can’t pay the debts, you are screwed (as so many crypto victims have found out to their shock). The money in a normal checking account is covered by a mandatory deposit insurance scheme, so you don’t have to worry about that.
Because custodial accounts replicate checking accounts, they can be just as fast and efficient, in themselves. Having to pay the upkeep of the blockchain in the background means, that they can’t be as cheap as actual checking accounts. If a custodial wallet offers you better conditions than a checking account, they must be gambling with the crypto (that you loaned them) in some way, that a normal bank is prohibited from doing with customer funds.
For the sake of completeness: Exchanges in more regulated jurisdictions work like stock brokerages. They must hold the assets. In case of bankruptcy, they are special assets that belong to the customer and are not used to pay creditors in general.
While Lightning doesn’t need you to open a channel for every new recipient and has smart routing through other participants, I still think it’s an inconvenient solution we don’t have to take.
We have Solana, a 300.000+ TPS Layer-1. We have much smarter Ethereum Layer-2’s that don’t require this bullshit. We have many ways to tackle this problem, it’s the hyperfocus on Bitcoin that, in my opinion, makes people go for Lightning network anyway.
Solana is incredibly centralized compared to BTC. The higher the TPS on your base layer the harder it is to meet the hardware requirements to run a full node. Scaling in layers is the solution.
Eth’s L2s are a confusing mess. They offer a variety of degrees of security and decentralization, some of them, like Polygon, are a network run with only 15 validators, yikes! And many of them are secured by a single bridge. There have been plenty of notable bridge hacks, it is not fun when your currency gets depegged.
Solana currently has 1777 validators - which doesn’t look like much compared to Bitcoin, but is actually way more than enough for any practical intents and purposes.
You need the same infrastructure for any electronic payment system.
What you don’t need for anything is crypto “mining”, which is almost pure overhead. That’s what the article is about.
It’s not pure overhead. It’s the means of initial distribution and also mining is the backend for handling transactions. Not that I think it’s efficient by any means. It’s just that it was necessary for Bitcoin to ever become something that mattered.
Mining is barely transactional in nature. Pretty much all of it is calculating hashes, which, on one hand, is super important as part of Proof-of-Work consensus, the most decentralized one we have, but on the other we have other reasonably secure options that waste two orders of magnitude less power.
It’s not necessary to perform any of the functions of crypto, including money laundering. That makes it pure overhead; pure waste. There are offshore banks that facilitate tax fraud and other criminal activity. Crypto, somehow, allows exchanges to escape the scrutiny that falls on these banks. Objectively, there is no good reason why all this waste should let you avoid scrutiny of regulators or police.
This doesn’t mean we can’t do better than both.
We can do better than capitalism entirely. It’s just that we can’t. Gotta get rid of the mentality behind it first.

Crypto capitalism is super bad idea exactly because it’s uncontrollable, i.e. all the bad stuff of capitalist economy, uncaged.
It encourages money hoarding, which cripples the capitalist economy, it does not allow to control emission, which is actually bad because it’s essential to driving economy out of crises, it does not allow to block criminals’ access to money and transactions, it severely complicates taxation and other important economic actions.
Crypto capitalism has the potential to exacerbate inequality, and cause a giant slew of problems sending modern economy into chaos. But yes, your 500 ADA salary will be truly yours.
I’m pro-crypto, by the way. While posing new risks, crypto can be super helpful as means of unsanctioned money transfer, breaching artificial limitations, keeping governments in check by always being able to support protesters, etc. But making it the world go-to currency is a bad idea.
Ok, but thinking crypto won’t be widely adopted is just wishful thinking. Do you honestly see a reality in the future where it’s not widely adopted?
If so, I would be curious to hear how that would work and what would people use instead?Uhm…people would use traditional finances? Banking system ain’t going nowhere, and CBDCs make their turn - as dystopian as they are, it’s super easy to force them upon people.
What would be wishful thinking is assuming most countries will happily adopt crypto. And besides - that’s even more of a dystopian scenario.
What makes you think the FIAT system won’t end up in a hyperinflation? And if it doesn’t (lol), what makes you think people won’t wake up and realize crypto only goes up against FIAT and it’s fixed supply? And if we do get CBDCs (which I believe we will, especially since that’s probably the only way they can try to save and transition the current system into something that doesn’t implode), what makes you think people will just gladly welcome them and not opt out for the alternative (crypto)? I hold strong belief we will live in a hybrid CBDC + crypto world fairly soon.
