The reason i deposited the fund is to buy their TKP token because it is cheaper in BNB pair while ETH pair is higher, so i wanted to trade it alittle before withdrawing it. Unknown to me that i can buy but can't sell hahahaha.
Your main intention to take arbitrage chance from both of pairs but you have ended by getting scammer by exchange site itself. You must also know that if there was no liquidity in that exchange site and that makes zero chance to did arbitrage.
Trading only in the legit exchange site. Even if that will be more difficult to did arbitrage at least it can be trusted unlike this garbage exchange site.
