I'll start with the safety question. Huobi has never been hacked. Two-factor authentication and SSL encryption provide protection. The majority of funds are stored in cold wallets. The exchange claims to have reserves of 20,000 BTC stored in a secure independent wallet, and there is also an Investor Protection Fund in case of unforeseen circumstances (I hope I won't have to use it). This fact at least brings a sense of calm. Now about the fees. This is interesting (though not new) — the fees are fixed and do not depend on turnover, amounting to 0.20% for both makers and takers. However, for holders of Huobi tokens, the conditions change. If you have at least 10 Hong Kong dollars (about 100 rubles) in your account, the fee drops to 0.18%. At higher levels, the fee can fall to 0.07%. I withdraw funds through AdvCash; there are no other convenient tools.
