I'm curious. You're an academic, and a scientist, I believe. So any theory you hold must be falsifiable in order to be viewed as credible.
Under what criteria would you entertain the idea that you might be wrong about bitcoin, or cryptocurrency in general?
I answered this some 6,223,678,221 pages ago on this thread. "Success" will be when bitcoin (or crypto) gets used by a large number of people because it is cheaper/faster/safer/easier/whatever than the alternatives. Not because one has a BTC stash to burn, not to support the cause, not to evade taxes or make illegal payments, not because it is hip, not to speculate with, not out of curiosity, etc.
Offline key/address generation and asymmetric crypto-signing of "digital checks" are undeniable wins that I am sure will be widely adopted eventually. As for the rest of the bitcoin protocol, and the Satoshi blockchain in particular, I am more skeptical than ever.
