That is a one-sided point of view in my opinion. Yes the cryptocurrency space shows that people desire for something that is different from what they are used to, which is first and foremost something that does not support quantitative easing and also raises capital mobility on the individual level, but we shouldn't forget that we are also all better off if we do indeed have some tools in place to get fraud under control as much as possible without sacrificing freedom at the individual level. I know that is a dilemma and it can never really be fully controlled for, but it is in our best interest to find the sweet spot. Crypto has its own set of problems that needs to be addressed.
The financial crisis does not always bring positive changes, for example in my country. The crisis in 1997 has saddened us to this day, the exchange rate of the Rupiah which was stable against the Dollar is now very low when compared to the Dollar. The hereditary state debt has become the biggest burden to date. However, currently crypto does not provide the alleged crisis potential because crypto does not use a qe policy. Everything is left to the market and if banks adopt crypto then people will realize that there is no need for a central bank anymore. Because the whole economic system is rotten today is the central bank everywhere. They are regulators as well as creators of chaos in the economy.
