Hotbit.io is a great exchange for trading alts. They got new coins listed all the time. Just becarefull selling because the sell price is way above market prices. Even the exchange coin htb is goin to sky rocket. People will be trading this platform. It's so easy.
I see have to many new coins already listed there and of course Hotbit is a big exchange or still legit. it indeed is still far if compared to the top 10 exchanges but Huobit is a good exchange as the people here say. I have never traded on Hotbit maybe because none of the coins that I got were listed there, maybe I will try to use this exchange in another time.
For my experiences upon trading on hotbit I can say that I really don't find any issues since my withdrawals goes well and my traded pairs gone smooth but there is a controversy about bots or fake volumes, but actually I didn't care about that right now since it's been a long months since my I execute my last trades trade and never got any chances to trade again since my hold coins are not in that exchange.
