A Hong Kong exchange operating since 2017 has never encountered any force majeure situations, which allows it to inspire trust. For me, the main advantage is the speed of transaction processing. The exchange effectively handles a large volume of transactions, even though its turnover isn't that high. This means that orders are executed instantly. It's also convenient for BTC transfers, which are processed quickly and at low prices. In terms of security, everything is top-notch. You can withdraw your assets at any time without any issues, and their protection is ensured by cold wallets and two-factor authentication. Trading is also at a good level. The only downside is dealing with cryptocurrency-to-cryptocurrency pairs and the limited selection of markets. But for me, as a fan of liquid assets, this is quite acceptable. One of the features of the exchange is the possibility of mining. I don't participate in it myself, but the fact itself is impressive. Among the drawbacks, besides the mentioned pairs and the absence of fiat currencies, one can note the lack of some trading tools and altcoins. But there is no perfect exchange. I trade successfully here, mainly through the web terminal, but I also often use the mobile app for iPhones.
