Okay so here is my case. I had a recent Ether withdrawal from HitBTC. We all know the excellent swiftness of the ETHER network that any transaction with a good amount of gas will be confirmed within a minute at max. Even every exchange process eth withdrawals quite quickly. But here is Hitbtc. It has much more withdrawal fees than normal exchanges. A fees of 0.01 ETH while its just 0.002 on exchanges like Mercatox. But the main problem is that I processed a withdrawal yesterday and it took more than 24 hours for that withdrawal to get on the ethereum blockchain it was because they didn't even sent the transaction to network for more than 24 hours kept it to themselves.
the same thing happen to me but with Cryptopia but that's not a scam or something bad at all cuz the ETH network had overload , i'm not defending on HitBtc cuz they have no support and that's a strange thing, for now just avoid that exchange
