Re: I second that request.
Further to that, the term cryptocurrency is being used to describe what is quite a broad ecosystem of different things. Bitcoin and Ethereum specifically are expensive in terms of transactions (the cost to the user of the currency as well as the energy cost involved). If you look at more modern alternative projects (ADA, Solana, Algo...) they are significantly cheaper/less power intensive. A google search will tell you a solana transaction takes around 1837 joules, if you do a second google search after that one, you've used more energy than a solana transaction. The costs of that particular coin are low as well, 0.00025$ average currently.
By all means i agree that Bitcoin, Ethereum and other older technologies do need some correction but that said it seems to me that the economics of these alternative coins will eventually see them win out. Perhaps we shouldn't wait for the market to make that selection though and as such legislation would be the way to go.
