To be honest, I do not know which one to advise you. You can earn on any of them, the main thing is to know how to earn money, find a reliable mentor and learn from him. By the way, there are a lot of tutors on cryptocurrency in Instagram or on YouTube platforms, I think you should find the necessary information there. Also, I used to use Binance, but it's a hard crypto market for beginners.

I agree fundamental market analysis should be studied to try. By the way, my friend is also making good money on cryptocurrencies. He is registered everywhere, but recently he tries to open his own crypto exchange. By the way how to open your own crypto exchange because the process is complex. And crypto prices are constantly changing and exchange and trading commissions are also changing.
