You seem to be a person of some means so I suggest that you hire, for your own benefit, credible independent experts on cryptography and distributed systems to give their opinion, because from what I've seen virtually all such people would not give a generally positive opinion.

That is, if you actually care about this sort of substantial question and not just about whether you can flip the coins for a profit.

Beyond that we will have to see whether the black hats of the world take an interest or not, when and how.
