Since this is science please make no discussion about how crypto currency is bad, I think we are all in agreement it's a giant waste of electricity used only for cp and drugs. Let's discuss only ways crypto currency could be destroyed. Would introducing fake crypto currency destroy the value enough to make it worthless, or would there have to be a more brute force method of destroying the program itself or possibly targeting mining rigs with viruses? I'm not a computer expert that's why I'm asking you people.
Yes, but purpose of any investment is to exctract money from the people, preferably poor ones. Market makers always make profit, that’s not relevant. What relevant is if poor people get burned, when all smoke and mirrors collapses, they’ll exit everywhere and liquidity in crypto is actually not there for simultaneous 200 billion exit. When dumb money disappears, suddenly the market is no longer so lucrative, and only main standing ones will remain somewhat relevant, like btc or eth. As for 90 percent return - commodities also swing by that amount sometimes
