No one can trust Bet-IBC, they are scammers. Also it's good to know that Acc-ex and Betting Software(BSO) are related.
They had huge hidden fees.
Some other broker may have additional fees, but at least they are written in T&C.
No matter which one you choose - asianconnect or premiumtradings, or any other. As long you follow the normal behavior everything will be alright.
