First of thanks for writing long and detailed blog on a complex topic. Cryptocurrency is the competition against banking curtails. Idea behind currency is the value it represents. When monetary policy enacts, it dilutes or contract that value. Ultimate problem is current currency system is that is based on debt and interest. As the interest+principle is higher than principle, one has to create more money to service the interest- a never ending cycle. Even cryptocurrency sometimes overshoots or undershoot value, but it is continuously evolving and competing with status-quo.
Yeah that point about the current system and the fact the interest on the debt are never created thus more money always to be created just show how malicious this whole system is.
