It was possible to write a fork that preserves the money without making a full roll back of the blockchain. Its technically slightly more difficult, but achievable, and you would know how if you would spend more time understanding this technology instead of doing price talk all day which makes crypto look like ponzi schemes. Have fun with your market cap so you can cash out at some day into fiat because you are not interested at all in creating an international currency.
Sorry but I fail to get your point... "Have fun with your market cap so you can cash out at some day into fiat because you are not interested at all in creating an international currency." Have someone made a vested promise to create "an international currency"? They have created ALREADY, a crypto currency that, by definition, is international. It is DONE. You can trade it. You can buy stuff with it... And there's a lot of people that want to remain invested (and staking) for a long time in hopes the value gets much higher, yes (your "market cap"). Many others, want to trade it for a double, a triple... or just 20/30% at a time. Anything specifically wrong with any of this?
Like I said, I fail to see where you could possibly be going...
You can also use USD everywhere on the world, as long as the counterparty accepts it, but this doesn't make it an international currency. A currency for the whole world is only possible if no single nation or small group of people is able to manipulate it. It has to be trustless.
