Why not just continue with the exchanges you have heard of instead of looking for another exchanges to make use of? Thats how some of you end up falling for scam exchanges. Binance and Coinbase are the biggest exchanges we have here, so we go the two of if youre interested in day trading, they are the best and thats why you heard about them first. Majority of the other youre going to come across are likely going to be scammers, so be very careful.
eToro[1] has this feature; pretty much they give you $100,000 of play money, and you can trade with all your heart's content without actually risking your money. You can also trade assets outside of crypto aswell.
Yeah eToro is going to be helpful with their virtual trading , he wouldnt have to start off immediately and start trading with his money and taking risks, although I have not made use of the eToro trading platform, I have been making use of Binance and Coinbase pro for long now. Heard that eToro also has copy trading.
Binance and Coinbase are already good choices for day trading exchanges and they are well trusted by most of the traders here. Since you are still a newbie in trading, i suggest to gather more information first and use a free demo account first so you will be aware of how a day trading will work and if you are suitable for it. Many have thought that day trading is as easy as that and can be much profitable but in the end, only few have succeeded and gain huge profits while others end up losing their capital.
