This is news to me. They are fully visible? Any source of that information?
Yes, page 15 mentions 614,305 BTC in commissions.
Afaik the amount in his private pockets isn't known, only estimated (and most likely way less than 600k).
Of course it's less, DPR had some expenses to cover after all, and some of those were paid when BTC was worth much less than today.
