Cryptos are what facilitated the growth of blockchain tech. Without the cryptos, we still have blockchains (but definitely not ones with smart-contracts or self-governance mechanisms) but instead ones that no one cares to build or deploy anything on, because they aren't secure, decentralized, and without any efficient rewards mechanism for participating (i.e. cryptocurrency, because I have no idea how you involve fiat as any sort of native or base payment token), then there's no growth.
People confuse bad people with cryptos. They are unfortunately a useful tool for bad people, but after all this time I can't really sympathize with anyone buying shiba-moon-cum coin/NFT or DeFi yielding rocket-dick-token for 20,000% APY and then losing everything.
The point I was making though is that - and this is not directed at you specifically but for those that keep bringing it up: the energy argument is dead. And the fact people still bring it up is the equivalent (to me at least) of 75 year old politicians making choices on modern matters that influence the lives of prime-career millennials with their entire lives still ahead of them. If/when the market is freely allowed to determine that yes PoS is undeniably better than PoW, then even Bitcoin will be forced to evolve too.
So those who don't know what they're talking about should just leave it alone. Otherwise they contribute to trying to shackle innovation and slow this entire process down. And for what? Because they missed the boat? Or maybe it's because they really truly care about a major pipeline being ransomed 8 years ago, but seem to conveniently ignore the pre-school level of cyber-security that major pipeline had deployed. Or maybe they truly believe the 0.5% world-energy consumption of Bitcoin, much of on renewables, is the main cause of climate collapse... which brings me back my 75 year old politician analogy!
