I will open accounts on some exchanges soon. I would like to prioritize one where I will be able to practice for free. From what I have read and seen so far, Binance seems to be considered the best exchange overall. However, I didn't see any mention of being able to practice for free on Binance website. So which exchanges would be best for that?
Thats a good plan before you do an official trading, and you can try on HitBtc which I believe have the feature of demo trading. Trading is not easy mate, you should also read books, attend seminars and watch youtube tutorial because you can just know the system of an exchange but still your trading action will depend on your knowledge about it. If youre ready to the real world, then Binance is indeed the best option.
