In today's digitalized world that has seen the inexorable rise of the internet and its related technological advances, it was only a question of time until our financial system would be improved upon by digital technology. The emergence of so-called cryptocurrency, with Bitcoin undoubtably being the most prominent one, has therefore subsequently led to new ways of payment and storage of money. Especially Bitcoin, however, has had its fair share of illicit and criminal activities.
