Over 2 percent of the US’s electricity generation now goes to bitcoin

  • What an absolutely absurd waste of resources. There should be some sort of enforcement/restrictions of energy usage from these clowns.

  • Eth has moved to staking, which is good for the environment because it doesn’t have a bunch of computers competing for transactions, unlike bitcoin - instead the network picks a computer for the transaction and takes staked coin if the computer does something nefarious to the transaction. The problem though is that staking requires coins / money. Mining requires electricity and can make money (albeit pennies depending on your setup and electricty costs). For this reason, it’s not just bitcoin that’s a problem, but a whole bevy of other mining-based coins like bitcoin cash, cudos, etc. That problem (the desire for folks to spin up new farms to mine crypto coins which they can mine using the spare CPU/GPU cycles) is likely not going to go away soon.

    • The benefit of PoW is that it is tied to real world physics and markets. The price of bitcoin is derived from the price of electricity, computing power and the supply. PoS is tied to the price of what the owners of the coins will sell them for and who wants them, in ethereums case there’s an unlimited money printer that could crash the price at any moment - like the usd, but the usd has a huge ass army behind it

        Eh.. physics in the sense that faster processing means faster processing but it’s a very wasteful process. It’s like ordering a meal from hotel room service and having 100s of people bring you what you ordered. Proof-of-work-wasted.

        The price of bitcoin is derived from the price of electricity, computing power and the supply.

        There’s a huge part of PoW that is left up to chance. Individual miners will spend lots of money on an expensive rig and get pennies. Some miners will join mining pools to split the wins but those generally are shared according to your computing power, so pennies. Pennies and unless you’re doing things right, huge electric bills. Hell, even death in some cases. There’s a chubbyemu video about a kid who ran too many miners in his room, which got too hot and he suffered heatstroke.

        PoW was great to begin with, but it is the reason why crypto has such a large carbon footprint.

        PoS is tied to the price of what the owners of the coins will sell them for and who wants them,

        Can you elaborate? I think you (or maybe I) am misunderstanding how PoS is priced. From what I understood, it was loosely tied to bitcoin (because investors will diversify into both coins and bitcoin has much more volume / market cap). As I understand, all cryptos are priced at what a buyer would pay for it. It’s not like BTC miners can ask for more money because the price of electricity went up. I don’t think 1 BTC would sell for $1,000,000 USD in 2024 just because it was scheduled to do so. If a competitor to BTC came out and was better (e.g., SEI) I think that would affect BTC’s price. I don’t see how ETH would be any different.

        Proof of Stake at the end of the day is just saying “instead of joining a mining pool and paying my electricity and hardware to do a lot of wasteful work, I’ll instead pick another entity to do the mining for me and give me a share of the profits”. Proof of Stake is still Proof of Work, it’s just sort of a curated proof-of-work where the network picks one machine at random to do the work (depending on the amount staked with / trusted in that machine and the administrator of that machine). It works well enough to provide an estimated APY in lots of cases, which isn’t something you can get from Proof of Work mining BTC.

      • Ethereum does not have an unlimited money printer. It has a specific inflation rate and network protocol controlling it. Its fiscal policy has changed over time, PoW is better, but you don't have to make stuff up to make that point.

  • To those that say this is a waste and has no good purpose, you should know that most energy used by miners is renewables because renewables (especially during off-peak hours) are the cheapest source of energy.

    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.

    The energy used by miners is needed to secure the Bitcoin network. Historically, we have built currencies of incredibly inequitably distributed resources: precious metals, stable governments, etc. Bitcoin was the first one to build an economy based on pure energy. This stuff literally falls from the sky. While it is not perfectly equitably distributed, it is the most equitably distributed resource on earth that can be used for this purpose.
