I have faced this problem once too and I can share my experience. The first thing I paid attention to was security. Choose a platform with a good reputation that has reliable methods to protect your data and funds. I started by reading user reviews and recommendations on forums - this really helped narrow down the list. The next point is the user-friendliness of the interface. I have tried several platforms and, frankly, some of them were too complicated for a beginner. A user-friendly interface makes the trading process much more enjoyable. It is also important to pay attention to the fees. Each platform has its own, and some can significantly affect your profits.
