How do you think: does crypto make criminal life much easier? We all know that criminals use crypto to sell drugs, guns, people and everything else. Did crypto make doing such things easier? Earlier criminals had to think how to keep their anonymity and get paid, how launder their money, how to not get catched with this. But now they can just use crypto and all the headache about this financial troubles passed away. Of course there is much bigger positive points of crypto and not every user of crypto is a criminal, but anyway are you worried about this? Criminals also worsen the reputation of crypto that is not really stable itself.
Until now I still believe that crypto is only a tool, as long as people use it in a good way, crime will never occur. We can't control crypto but use it in a good way is worth doing. Just ignore people who use crypto for crime, because bad people have been present before crypto was born.
