China has been tightening it's rules in regards to overseas investments.
And as a result of that in the last quarter of 2018, over 1b of USA real estate was sold by Chinese investors.
So what happens when the country with the biggest debt globally, starts to lose investors?
With a stock market in a downward trend, it doesn't look good.
At the end of WW2 the UK lost it's "global currency" status due to war debt.
All it will take for the USA to lose that status is for other countries such as Russia or China or India to start buying oil using something other than the US dollar. And that is happening.
So what will replace the US dollar as a currency of international trade?
It may be gold, but that is heavy & difficult to transport.
It may be 'paper gold' but there has been more of that printed than there is real metal.
Which leaves BTC as a main contender. Unless a new global, gold backed crypto emerges.
But given how long BTC has taken to establish it's self, that may not come soon enough, as things are moving fast globally as far as economics in the fiat world go.
Which gets back to BTC being the obvious choice, even though it is slow to process, and not the most modern of blockchains, it does look to be in the front seat for the time being.
