Someone would invent some other blockchain. Like when people invented a car. If that guy didn't invented that year someone would by now. Without crypto I would be doomed, because I don't like stocks and it would take me the whole lifetime to earn some serious money.
If bitcoins was not created then there will be no cryptocurrency that will be in the market today and the amount of wealthy people will be decreased since there are young gentleman who are lucky to believe and invest on bitcoins when it was still very cheap.
