Lovinbitcoinusers, to clarify some things first - did you buy that coin on YoBit (BSTY), and then try to send it from YoBit to your wallet? Or you have BTC on your YoBit account and someone is using that coins to buy BSTY and withdraw from your account?
I think you just send those BSTY and now you do not see that transaction on BSTY block explorer, but maybe this coin is not show transaction instantly, just wait to see the first confirmation on YoBit and also in your wallet.
