The IRS is stepping up their game. They've already seen Bitcoin go 3x and I imagine they are expecting even more gains.
America would never ban Bitcoin. The goal is not to stifle technology, but to continue milking their debt-slaves. Coinbase (Goldman-Sachs) will be pinnacle in helping them retain control of this digital future.
Hopefully. Donald is a bit of a loose cannon though and he already issued an executive order banning the petro for US citizens. I wouldn't be shocked to see him try and do the same with bitcoin stating "national security reasons".
