If this is the guy I'm thinking of he wasn't a "trader" he coded the first GPU miner back in the early days and just considered it a fun hobby project so spent it on pizza and other small purchases.

Very common type of story. I bought Bitcoin way back in 2013 but didn't think to save any. Spent all of it.

Jeremy Sturdivant and Laszlo Hanyecz are trailblazing heros.

Imagine accepting Bitcoin at the time.

He did, he bought 2 pizzas for 10k bitcoin and did it numerous times way back in the day.

true story, man. all of the early bitcoiners were weird nutsos.
