I was involved in the very early Bitcoin days, and it started for me as something else to do with lots of spare GPU cycles, then I started learning about the underlying tech, which I thought was quite an elegant solution for p2p trustless ledger. I still think it is.

I have not been involved for a long time though, as the original feelings I got from those early days and the community back then seems to have changed completely. Now its all bullshit shell games and scams.
