Yeah I don't regret it. I do regret not investing though. Around that time I actually wanted to invest in BTC too, thought at the very least it had a use case for the kind of stuff we were using it for, i.e. black market stuff. So that in itself gave it value. Talked to friends and family about it, and they all convinced me it was a stupid idea. So instead I held off.

Lesson learned, don't take investment advice from people who've never invested in anything themselves (and who didn't even know what Bitcoin really was at the time) in future
