Yes, it has been turned into the biggest debt bubble in OUR history...And all bubbles pop....People holding on to FRN's will watch whatever wealth they felt they had turn to zero.
And don't get me wrong I like the idea of cryptos, but ALL currencies need to be backed by physical wealth. And given that you are never able to actually physically hold your BTC then you run a very high risk of that currency falling into a centralized program that is controlled by lets say - the IMF, or even the UN....And this has been the centuries long goal, to create a centralized, one world government....If they accomplish that you will never have access to your btc again..or any money for that matter..
