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.
