At the end of the game they have to exchange into fiats. With a very deep research in blockchain that could be a trap for them, because it's allmost impossible to fake a real bank account. So how they will get their money? I guess, they buy expensive items in a store for coins anonymous (disposable cell phone) and sell them later. That's the only way, I can imagine.
But another question is: How to get the webspace, if you have to pay for it with your bank account? So why you don't ask the provider of the webspace to get their real identity? Well, the real identity belongs to an 90-years old blind woman in the slums of India, who knows nothing about Internet nor Bitcoins, nor that she ever owns a bank account. *lol* But wait ... I've made a thoughts error, because with that account the scammers don't need to buy and sell items for coins and fiats!
So say goodbye to your investments, if you don't want an old innocent woman to be arrested.
