What is the most significant thing you've changed your mind on with respect to cryptocurrencies in the last five years? Making predictions with certainty, under-estimating the resilience of Bitcoin, the social attack / argument surface. If you were to make one change to Bitcoin, what would it be? I would like to see more implementations of privacy features, which is already happening. However, no one person gets to make changes to Bitcoin. There is not much else I would change in the original design; I think it would be hubris even for me to say I can do it better. There has been a "next Bitcoin" that fixed supposed fatal flaws ever year since the beginning of Bitcoin, but none have superseded its design choices aimed at security, censorship resistance, and decentralisation. (And no, market capitalisation is not a great measurement for comparison.) This is a question from the patron-only live Q&A which took place on February 24th 2018.
