omg. just transferred money to them. btc. not fully confirmed yet. How can i cancel it?
no you can not do that because you already transfered it to their wallet.
just wait or send a ticket to them(usually they did not answer it).
you should have know cryptocurrency weakness is its irreversible transaction right ? please do your own research before doing it.
and stay away with this kind of exchange.
Yobit,HitBtc,Poloniex and many more.
they're trash and did a shitty thing behind their costumer many times.
