I do not think criminality is due to bitcoin. it depends on people who use bitcoin as a way to commit criminality. Many public misconceptions about the many uses of Bitcoin by criminals, but the thought is wrong thinking. This thinking is caused by the many people who think that Bitcoin is anonymous, people think bitcoin is the source of the criminal act. paper money can also be used for criminal acts, such as buying forbidden goods ... or using it to hire criminals. bitcoin is not used for it.
