I have been trading on CoinW for about a year. As for the downsides, I can mention the occasional poor localization and some minor interface issues. Some of these points are being fixed over time. Overall, it's acceptable for an average trader. There is no forced verification, TradingView is available, there is a native token CWT (which can be used to reduce trading fees), a wide selection of cryptocurrencies, and P2P options. Trading is smooth; I regularly withdraw my earnings to an external wallet, and there have been no bans for made-up reasons.
