I think you can start with small amount accordingly if you fail you don't lose much
Well thats true in day or daily trading is we will only just need a small amout may be 200USD or 300USD is enough to start but for me it will take too long until you can earn many money in day trading if you are begiiner in trading, bit if you are expert in trading you can do well in day trading, but for me its jist a little bit risky.
