I’ve seen that in practice. A non-crypto fintech I was at was acquired by a traditional lender and a number of staff took off immediately after the acquisition. A bunch went to FAANG (or FAANGish) places and a bunch jumped to crypto shops. In general the ones who jumped to crypto were either pure promoters or were able developers who had no understanding of finance, economics or the payments system.

It's more (iii) the narrative.

Give us your money to invest in this new, fresh face that's going to change the world.

If you're an old face - why haven't you changed the world already?

The story isn't as catchy.

It has nothing to do with what makes sense. For a large subset of VC (obviously not all) - it's more about what you believe you can sell to others than what you believe is actually going to succeed.
