There are plenty options how to evaluate crypto exchanges but one of the most important point of view should be security and solvency. Huobi, is one of the exchanges without any issue, scandal or hack, that means that they have raised security to decent level, is compliant and listen to the customers. On top of that there are almost all features you know from other exchanges which involve their own token and own chain, derivatives (include also warrants), spot trading, earn (staking - flexible and fixed), fiat onramp, own DeFi wallet and some more. The trading fees are slightly higher but still reasonable for the offer. There are a lot of promotions which can get you free tokens (this will compensate fees). The best thing is that for new users they have prizes up to 300 USDT if you use refferal link. The liquidity is high enough and there are a lot of users. Overall it is a great choice to start trading crypto.
