Do you need to be honest here, why did you need to give someone else money to make a bet for you? this may be in line with what @Betcoin.AG theory is saying unless you can prove otherwise, your track record of using someone else to place bets for you can make you suspicious and there is no way to accuse @Betcoin.AG of being wrong. sorry but the situation is in favor of @Betcoin.AG in this case
I also commented in the other thread and I think in this case the OP is not right. It sounds a bit tough to say it, but it seems to me that the OP is finding the problems he has been looking for. Giving your money to someone else to bet is on the one hand very naive, and quite likely to end up scammed, and on the other hand suspicious as you say.
