I once read an article that says bitcoin is used as a payment transaction for terrorists and hackers. And maybe you guys in this forum also already know it. But here i want to convey my personal opinion in that matter. I think that internet and bitcoin interrelated. Many terrorists and criminals use internet .so also with bitcoin which used perpetrator However, despite all these issues, do people make concrete efforts to ban the internet? No. Not because removing and banning Bitcoin is difficult, but because the internet offers more positive than negative. For the same reason, we have to be more careful about our mindset for Bitcoin, because much evidence has shown that Bitcoin brings many positive, if not more, effects than the internet. Internet and Bitcoin are just devices that 'bad guys' and 'good people'. Fortunately, the world is filled with more people in the 'good people' category.
I certainly believe that it is possible. For some criminals who are not really as famous and as others, using bitcoin is a possibility because they are not entirely known all over the world, thus allowing them to use a wallet and providing their personal details. However, for those who are really famous for their heinous crimes, it might be difficult without giving in some personal details.
