I do not know how bad people do their dirty deeds, but I do not like it. I do not want to be blown up somewhere, or that the bus killed me.
There is a cryptocurrency or not in the actions of bad people, if they want, then they can always do bad things. Otherwise there would be nothing terrible now.
The most terrible is nuclear weapons, which the United States, China and Russia are actively increasing. It's not clear who uses it first.
