I joined a mining pool in 2010. Shits and giggles, you know? But my wallet was on my first SSD (a technology for which by this point we had no idea on longevity), and I wasn’t good about backup hygiene. Anyway, long story short, I had 4 BTC when they were worthless. I’ve since learned to be more diligent about backups.

A thumb drive back then could have saved me from homelessness today.
