(I only pray he's got all those private keys... otherwise - trouble).
He must do jackshit, it's his money and he can do with it whatever the hell he wants.

Otherwise every "admirer" from a local bum with a clawhammer to town cops, to cartels with bazookas will be coming after him & his family. For the untraceable billion dollars as mentioned elsewhere.
Gods help this man
