I guess this is another "Bitcoin should be the new world reserve currency" thread.
I think it`s more possible to return the gold standard instead of adopting btc as a reserve currency.
The USA would never lose it`s monetary advantage and will never let some other national currecny to dominate the world.
And by the way,bitcoin can be destroyed.
good luck with destroying the 1000's of alts each with better and evolving tech out there......you would merely hasten the evolution to a better more powerful solution than BTC. In fact I think this is the exact reason gov's will not try to destory BTC itself as they see the tidal waves or alts ready to go. In-fact BTC is giving them time to get a position.
So no crypto won't be destroyed at this point.
