I'm in the same boat as you, one of the classic stories of "I mined double digit numbers of Bitcoin in the early days when it was literally worthless"... eventually wiped the hard drive that held the wallet and sold the computer without a second thought.

I'll be kicking myself for life for that, but I also have to remind myself that if I had held onto those worthless coins worth fractions of a penny, I almost certainly would have cashed out well before they were at their peak value, and spent them on a pizza or some darknet weed or something else dumb. This at least helps me cope with knowing what could have been...
