It doesn't matter if Bitcoin exists or not, you would still have to deal with the China trade imbalance regardless, either through war, tariffs, or each nation adopting the same currency to prevent currency wars from creating the imbalance. Tariffs and war are likely a synonym for each other, so the end result is, you can likely either all die in WW3 or adopt the same settlement currency. The only viable candidates are Bitcoin and gold, but both could obviously be used at the same time to make up for the deficiencies of one another and everything would just be a BTC/Gold trading pair.
If I were the head of the Rothschild JIDF financial cabal, and I controlled half of the worlds real wealth, had various governments across the globe dangling from my finger, and was capable of sending them to war with each other in order to satisfy my own geo-political or profit seeking objectives........why would I allow my great wealth and power, to be priced in Bitcoin, which is owned and controlled by a bunch of grubby little Chinamen?
Crypto is in it's infancy r0ach, and whilst I can forsee some digitial based crypto coming to dominate global finance, Bitcoin just aint gonna be it. Bitcoin is a prototype. Furthermore, if humanity ever gets to the point where some crypto is the global digital currency, then humanity will come to despise that digital currency, as it will be a tool of global enslavement. A centrally controlled one world currency, all transactions traceable, with the central authority capable of 'hard forking' any wallet (contained within an implanted RFiD chip?) belonging to any individual or group that they do not like. All sounds a bit New World Order to me.
