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 in 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.
The negative impacts of the existence of bitcoin one of them are for crime because of its bitcoin nature is anonymous, but in my opinion, it is an issue that is developed so that bitcoin falls. Maybe there are some who use bitcoin for the crime but the number is not much.
