This is the issue that was being thrown by the EuroPol and the UK Metropolitan Police. According to them bitcoin has played a huge role on the increasing criminality in their area. They added that a huge number of cybercriminals were using bitcoins in their activities.
This just shows that as bitcoin develops both advantages and disadvantages will tag along.
Yes, in my country Bitcoin is banned by the government but many people want to participate in this currency trading because the returns are very high, with the current green market situation likely to be similar. The hybrid of these coins is very developed.
