America has always tried to control any kind of capital, whether is it property through taxation, entrepreneurialship via permits and licensing. If they can get their hands on it, and setup "official" paths to enter into any field, they arbitrarily set prices, enforce taxes, and charge fees.
However, pursuing cryptocurrencies will have difficulties, but it can also be the solution to government intervention. Sometimes it takes people who will say, "No! I will not do it your prescribed way, and I won't seek your permission to do it a better way." This is how you take back freedom and institute economic expansion.
Thanks for the post @cryptofreedom!
