I choose Gate.io for trading altcoins and tokenized assets, which are indeed very numerous. There are lending systems and cloud mining, but I haven't used them myself. The fees are market-based, with an average rate of around 0.2% for makers and takers. The TradingView terminal is convenient for analysis. I want to point out that there is no support through call centers; you can only contact them via chat. Overall, this exchange is suitable for portfolio diversification; I have tested transactions on 9 different coins over 4 months.
