just tryed moon bitcoin and most possibly it is scam. i am trying to claim prize and it says that there is too many similar requests. about 100 times by now. scam.
It is not a scam. Many of us have been using moonbit and getting regular payouts for quite a while now.
Most likely the problem you mention is do to xapo being more busy than usual as other sites which
payout using xapo have been having a similar problem.
Do you use the xapo payout option?
Just try it again later and you should see a payout.
I just checked it and got that error message and then immediately re-tried it and had a successful payout.
