> Crypto is a needed option, it can be made to be more environmentally friendly. This argument has never made sense to me. BTC is fundamentally proof-of-work, and attempts to switch it to some other “green” mechanism will almost certainly fail (see Bitcoin Cash). Ethereum has been promising PoS for nearly as long as ETH has existed. Other “green” coins are either tech-demos, ponzi schemes, or some amalgam of the two. The ball is rolling, the train has left the station, BTC and ETH have the momentum. Other than rug-pull incentives like airdrops, why would those in the “circle of adoption/need” choose green crypto over what is established?
