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?
You can practice trading for free on
eToros demo mode. And because they are a social trading platform you can also copy more experienced trader once you have built up some confidence. Good Luck!
Copying any of the pre-existing traders might not really need any confidence. What you would need is to find a trader who has good portfolio, good ROI and also you have to check the number of people copying the trader. Understanding these basic things can make you copy any professional trader and earn a decent amount but you need to pay some fees which would directly be transferred to the trader you are copying and also you would need a good capital to invest on such traders.
It would be good for OP if he starts learning trading on his own because it would not cause him any extra fees and also he might perhaps get higher returns if he move onto real trading with immense knowledge and experience.
