> To me, seeing crypto on a resume means the engineer is a true believer in viability of crypto, and therefore not smart enough to do well in a big boy company.

I don't believe in crypto myself - but your statement sounds a bit egotistic. Should employees work at a crypto company (such as CoinBase) only if they truly believe in crypto and not for say, a good pay? The second statement about smartness too, doesn't seem like a good thing to say.
