Do you express the same curiosity when it comes to the use of cash for criminal purposes? By the way, cash is far less traceable than Bitcoin when its used for illicit purposes. Criminals also use cars - should we ban cars?I think it's a valid question to ask.....
In what you cite above - you make my point for me. The bankers started this tar and feathering way back. Yes, cryptocurrency could be used for nefarious activity but that doesn't define it. It's analogous with the internet being branded as an exclusive haven for pedo's back in the day - perpetuated via ignorance.
When you and others brand it so - I'm more than entitled to point out what has become glaringly obvious to many. That the vast majority of illicit funds are laundered and moved around via the traditional banking system. They're facilitators in that.
