With all due my respect, I actually want to make " Scam Accusations " for crazybtrade. Without further ado here may already proven REFERENCE 
Is not scam. You tried cheat us.
Use double spends and transactions spends an input which is unconfirmed.
Your 1 bet is really, 9 bets is fake.
after my post, he confirmed transaction but he want cheat our game.. our game not pay winnings to cheater
You're an idiot, don't understand how bitcoin works, or just want to steal customer funds. It's perfectly normal to spend an unconfirmed input. Sites that process many withdraws in a short period of time do it all the time, like my Cloudbet, Poloniex, Fairlay, e.t.c withdraws. If you're accusing them all of double spending (and probably many other sites as well), please find an transaction that they actually double spent and accuse them of it. It's pretty serious if your claim is real.
Cloudbet, Poloniex, Fairlay, e.t.c ??
idiot? i think this you are..
We not accept exchange or shared wallet, you will not receive the payout to your address as you do not have
control of this address. especially, you have not to use coinbase, xapo wallet.

in this case it is clear you don't really know how bitcoin works and yet to planned to run a gambling site? unconfirmed inputs doesn't mean double spend idiot. don't run a onchain gambling site if you don't know what could you face, unconfirmed inputs are not means of cheating. you even gave a link explaining what is unconfirmed inputs but did you even read it?
