A few thoughts:

The US and China have yet to weigh in on the use of BTC in their respective national economies and/or the global economy.

Mining companies are leaving China because of fear of government interference. Their fears are well-grounded.

There is no operating solution -- yet -- to the elimination of BTC rewards when there are no more coins to mine and miners have no opportunity to earn more from mining. And, the original Satoshi White Paper contemplated the need for trusted third party intermediaries. There is still much that can happen.

Expect BTC to rise as a legitimate currency option in nations in which inflation is rampant.

Down the road, as an increasing number of underdeveloped countries adopt BTC to facilitate their economies, the world will divide between fiat and digital currencies. Don't expect the fiat currencies/countries to surrender without a fight.

Please keep writing.
