We all miss chances to make some money every day. Getting in to BTC early is a big obvious (with hindsight) one, but there are thousands of others. Regretting missed opportunities is a total waste of time. Spend your energy looking forwards for new opportunities that you then won't miss.
I feel the same about it as I feel about most of the economic system. It's a disappointment that we as a society are still so focused on greed and wealth.
So yeah, no change in feels. I don't really care for money, have left six figure jobs mining because they made me feel like a scum of a human. Zero regret.same goes for participation in crypto, I had coins. But got out like 3-4 years ago once I realised it's cancer with no benefit to society as a whole lol. Zero regrets.
