being blown up in part by a growing lack of trust in conventional banking systems.

I would actually disagree; there is certainly a lot of money entering the space for that reason but I would say that that is not what is contributing to the overvaluation. Those who are investing in this space for the long run (those who are convinced by the security and governance) are going to be here through the bubble. I am targeting investors who don't understand what exactly are investing in other than their last investment's 300% returns.
