Few of my friends are regularly using Gate to buy some shitcoins and I don't remember them having any kind of issues so far, but what they did is very sneaky and shady. I mean, to enable deposit of the currency that you can't trade for anything and then set ridiculously high minimum withdrawal is basically an entrapment. And then when you add 8!! RBTC fee...It's something that not even shitty exchanges like Yobit and HitBTC would do I think.
One can argue that it's your own fault for not checking for what you can use RBTC for before depositing, but still, I wouldn't expect this from any exchange that cares about their reputation.
@Arrrvin I am curious now, what are the RBTC withdrawal fees for RBTC on Bitfinex/Kucoin?
