I don’t share your rose-tinted view of Bitcoin. It is almost entirely used for purchasing drugs and other illegal purchases, for laundering money, and for paying hackers to unlock hard-drives encrypted by crypto-virus attacks. The world should enact laws making it illegal to trade in all cryptocurrencies and forbid banks and financial institutions to convert them to cash.

That way this insidious evil can be stopped in its tracks, hopefully bankrupting those who have invested in this inherently worthless currency.
