Bitcoin is no threat to government or fiat currency. All government has to do to stop Bitcoin is --- nothing.
Simply wait and allow reality to sink in. Under no circumstances should government move to regulate the Bitcoin "market". Nor should they allow government insurance programs (FDIC, NCUA) to be applied to Bitcoin in any way.
Regulation would do nothing but add respect and credibility --- things that are otherwise sorely lacking.
This is not to say that the fraud that is occurring with so called "stable coins" should not be prosecuted. Exposing this will directly impact the Bitcoin market but it is not regulating the market.
