BTC, the War on Cash, A One World Economy!

Ok, so it starts of with bitcoins, then Venezuela suffers hyper-inflation, they turn to BTC… Alls good! Then India in the name of worthless money cuts the 100 rupee, they too turn to BTC. As a nations economic systems crash, BTC picks up as a savior, pushing up the price of-coarse. We hodl'em just for that!

Now BTC is not gonna hide anytime soon, for many people will/or use it as money already. So my ? is:

What event will have to happen in the USA, to push BTC as currency on the American people?

The USD is going to have to go eventually, no???

thoughts anyone!
