Ok, let's not waste your time (mine can be wasted ).  But I just want to say that I am closer to your position than you think, and that I don't think that crypto is ONLY for dark markets, but for those places where centralized systems cannot go, or became too corrupt to be efficient.  Your belief in the corruption of these systems is maybe different from mine.  I think they are corrupt, but not to the point where they have lost so much efficiency that decentralized systems can compete, except in niche applications.  Of course, the day that they break down, decentralized systems will have a large ecological niche to take, but today, that is not the case yet.

The idea that bitcoin, or whatever decentralized system AS OF TODAY will compete to death fiat currency without major crisis, is ridiculous.  Of course, you can count on the big crash coming.  Sure.  But your experiment will not give any results of significance before.
