This is the second post about the US Dollar and problems with Central banking that i've read today.

Whilst I advocate crypto-currency and its libertarian leaning principles.
I also understand that central banking has lead human kind to where it is today. People love to entertain the idea about 'fairness' but in reality, it simply doesn't exist because humans were not born equal.

Even though today, the dollar is no longer backed by gold, it is still the reference currency. When Bitcoin hit the lows in 2015 and stayed there, the monetary value of it was lower sure, but in all other metrics of measurement, it was clear that it was becoming more widely used.
Just like with every top crypto-currency, it's value is underpinned by Bitcoin because Bitcoin serves as it's gateway into fiat.

The dollar functions similarly. So in my opinion, they can keep playing the deficit game indefinitely. Credit expansion is what gave rise to people having better lives, even if it means we all have to suffer a little along the way.
