Bitcoin Q&A: Reflections on the last five years

Bitcoin q&a: reflections on the last five yearsWhat is the most significant thing you’ve changed your mind on with respect to cryptocurrencies in the last five years? Making predictions with certainty in a new and fast-paced industry; under-estimating the resilience of bitcoin [BTC]; the social attack / argument surface.

If you were to make one change to bitcoin [BTC], 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 [BTC]. 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a “next bitcoin [BTC]” that fixed supposed fatal flaws ever year since the beginning of bitcoin [BTC], but none have superseded its design choices aimed at security, censorship resistance, and decentralisation.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.)
