I don't think he has his entire personal stash in self custody but with the amount of energy he put into learning and reading I doubt he has 0 in self custody. Even if it's only 1% of his stash... (rumors 10-20k Bitcoin) ... He has more than most people on here in self custody.
It’s a hot wallet on a laptop running Windows XP and Internet Explorer.
I didn't say it was secure or well done self custody 🤣
It’s on his spank machine. 😂 I did hear somewhere that Microstrategy had an in-house custody solution where a certain percent of the stack was. I have no idea of course, but fun to speculate for shits and giggles.
