Likewise, UMG, just like Bitwinup, is scam protected, since the house, is profiting off taking a small fee, and not interfering with users, bets.
This, like, many, other, statements, in, your, OP, is, a, blatant, lie. House, edge, does, not, protect, from, scams, and, trying, to, claim, otherwise, makes, you, look, even, more, of, a, scammer.
Any reason nobody has opened up a flag on the OP? Looking at what is going on and what they are claiming it seems like one is needed.
Personally, I have not dug enough into it to see but from a quick glance it seems others have been looking at the site and coming up with a lot of things that are wrong with it.
