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.
Hotbit have more than 381 coins on its exchange. This would definitely be a good opportunity for the investors who are looking for new coins to invest in crypto market. total trading volume on Hotbit is $110,162,065 USD which is quite good. But i can't say anything about the authentication of the coins listed on it. Many of the coins are shit coins and I never advise anyone to invest on it. Otherwise Exchange is good, easy to operate and user-friendly. I don't see any major bug or difficulty while using it.
