> You trust random people on the street? All the time, no transaction is possible without trust. The crypto enables one sided trust, i.e. the payee doesn't have to trust anyone but the payer needs to trust that will receive whatever is promised. You pay your ransom with hope that the attackers will unlock your files, the attacker doesn't have to hope. When you build traditional system over crypto, you don't use crypto. Like exchanges basically being unregulated banks that might just disappear with your money. Your money is now gone because you wasn't using crypto, you were using an illegal service and you were paying with crypto and that's what crypto is good for.
