Sure.
I just hope he didn't spend everything, and was wise enough to keep some until the value grew.
(I've read this thread but IIRC it wasn't clear if he did)
Laszlo states in this thread that he
can't mine thousands of bitcoins a day any more. As I understand it, he was only able to mine
hundreds of them at that time... :-)
So I'm really not afraid he had spent everything.
