I don't think many scammers are smart enough to make that much money daily to be honest. It's the business owners and speculators that can reach these sums more consistently.
Smart enough? scammers are lazy and hardly every smart and that's how they get caught the majority of the time.
To be fair, scammers who work with cryptocurrencies often need to be quite skillful programmers. Unless they go for the Cryptostocks kind of scams.
Plus they very rarely get caught.
