they're manually sending btc.
mine took 5 hours.
also 2mbtc fee is too high.
of course, they had been tell you if you wanna deposit or withdraw it's take longer,
because they work manually to withdraw and deposit,
and bx.in.th have the worst fee ever
0.002 btc for withdraw.
the fee are so high, but there is still a lot of problems. not recomended
