I've been on this exchange since September of last year. I can say that I really like the simple, intuitive, and customizable interface. It's convenient to edit orders by moving them on the chart with the mouse. So far, there are 5 trading pairs: perpetual inverse futures BTC/USD, ETH/USD, XRP/USD, EOS/USD, and direct linear BTC/USDT (here you can hold two positions at once and use unrealized PNL as additional margin). The speed is 100,000 transactions per second. There are no technical downtimes. 24/7 support is available. There are bonuses for registration and activity on Twitter or in 10 Telegram community chats from different countries.
