I would like to see some real, trustworthy, verifiable person here.... because if we will be talking about 1000K BTCs here it can become hot....
To clarify, do you need someone to actually hold those coins for you, or only make a judgment in case the two parties dont agree? Big difference; if its the latter you mostly need someone objective and rational. Since Im not aware of any lawyers frequenting this forum, Id pick a mathematician. Meni Rosenfeld? If the former, pick someone who is not likely to be tempted by 1K coins (*). GigaVPS comes to mind.
(*) Im assuming you meant 1K.. If you really meant 1M, I wouldnt trust anyone
, I wouldnt even trust myself!
