You can't really compare "size" in that way. It doesn't matter if there are 10 miners or 10 trillions miners; The transaction throughput remains the same. The amount of miners determines the power consumption. The more miners, the more secure the network due to the higher hashrate, and the more power is consumed. Less miners means a less secure network due to the lower hashrate, and less power is consumed. In other words, the power consumption is directly related to the security of the network. The amount of transactions is not.
This is true. But that doesn't really mean we should do away with crypto. Should we do away with electric cars because they are consuming energy on top of petrol ones? Keep in mind that the majority of electricity in the world is still generated through fossil fuels.
Just FYI, if you pay something with VISA for example, the transaction is actually settled a month later. With Bitcoin, transactions actually settle in 10 minutes.
I don't really know if Bitcoin is the most energy inefficient... Most miners use ASICs, which are inevitably more efficient than using graphics cards (like ETH) or CPUs (like Monero).
There is a possibility that Bitcoin dies in the far future, and PoS becomes the dominant method of blockchains. But in reality, PoW is more secure than PoS. And it is more decentralized, because PoS encourages hoarding while PoW encourages distribution of coins to cover electricity costs... I think Solana has as of now, the best blockchain that balances security, power consumption and decentralization. But we'll see how it goes in practice.
I agree... But again, there is a difference between the faults of a specific crypto, and the faults of crypto as a general industry. All individual cryptocurrencies have faults or limits. But as a whole, it is pretty much a healthy industry. If you really want to understand why, I actually recommend you read through this whole Twitter thread, if you have the time... It amounts to Tweet 45...
You're 100% right. It is hard to measure the amount of renewables used. Whether it dropped or not after China's crackdown... I'm not sure. I don't know many places in the world that have cheaper electricity than China, so the incentive is there to increase rather than decrease the use of renewables. But I have no data on that, so, it's speculation on my part.
It won't win easily in the eyes of the public. But then again... We are mining Bitcoin with volcanoes now. That seems like a good selling point lol.
If the world economy collapses, Bitcoin and other crypto are a lot more accessible compared to gold, even to the average user. That's assuming the internet doesn't go down with it. Hopefully, web3 will assist in bringing a foolproof internet. We'll see.
In either case, we'll have a lot bigger problems if the global economy collapses. After all, even though I think crypto will be of use in such a case, we can't eat crypto.
Well, the thing is that Bitcoin has been made to do the exact same thing, no matter what hardware power you throw at it. Ethereum is also based on that principle. That's by design for the security and decentralization.
The amount of coins mined doesn't necessarily have a correlation with the power consumption. The mining of the few that are left are going to consume a lot more energy than all previous ones combined. The rewards are decreased every 4 years, while the amount of miners have been increasing. So it's costing more power to mine less Bitcoin in the same amount of time. And it was designed this way to increase its scarcity, rather than it being an inflation machine like fiat currencies.
There are other projects out there that scale depending on the hardware used, rather than them doing the same thing independent of the hardware.
One thing that people often forget... Countless ASICs have been built specifically to mine Bitcoin. If we were to stop Bitcoin tomorrow, all that hardware, which cost actual resources to produce, is now wasted. Not only that, you'd have to get rid of all of them. What do you do with that? To the landfill? Burn them? Doesn't sound that environmentally friendly, does it?
