Well, my problem is resolved. Today Betcoin.ag returned my deposit to me. This is not exactly what I expected, but at least they were honest enough to return my own money to me. Probably, in this situation it is the most acceptable option for both sides of the conflict.
But I will follow how is things going in this topic because I received some privat messages from other players with the same problem.
I am glad that the problem has begun to be solved, now it is necessary that have settled the arisen misunderstanding with all users of service.
The decision on simple return of a deposit not absolutely honest in otnosheniy different players. As Bencoin declared cancellation of rates and return of a deposit that logically that take away a prize from the person who has won and return the made deposit. And here at the person who has lost and balance less deposit isn't cancelled for some reason by all rates and don't return a deposit but only the account balance. It isn't honest in relation to players as in both Betcoin options remains in profit I take away vyigrash and without giving the remains of an otproigrysh. If have accused the person of suspicious rates that cancel all rates at all such players and return the brought deposit - it will be so correct.
