You mean Jeremy Sturdivant ("Jercos"), the person who sold those couple of pizzas in that TX.
A year ago or so I was wondering what the lad has actually done with those 10K BTCs, and if he even conserved them to date. No such luck (for him), as he declared in the following extract from the below referenced interview:
Q. What do you primarily use bitcoins for? Do you still control millions of dollars worth?
A. Bitcoin as a currency is meant to be spent. Those 10,000 BTC made it back into the economy fairly quickly, around the time they were worth some $400. A ~10x ROI from simply trading in a different currency is quite good, even if that factor could have been higher had I held on to said currency longer. Naturally there will always be people hoarding coins, trying to get rich, and quite a few people did get quite rich, but they wouldn't have got that way without economic growth allowing it. To that extent my bitcoin holdings do usually measure in hundreds or thousands of USD, simply because I use them much as I would a checking account, to conduct business both online and offline when I have the opportunity. Notably the "humble bundles" and the attached store accepting bitcoins significantly bolstered my video game library.
He actually didn’t work at the pizza store, but acted as a reseller for the occasion (actually recalling it being Dominos and not Papa Johns, but that seems like a memory slip).
