Although there are traders who are actually successful in trading short-term with or without leverage, it's not for PLEBS like US. I discourage fellow plebs from "trading", but if you truly believe that you could profit as a day-trader, then to measure your success rate, make a pretend purchase in Bitcoin with 100% of your trading capital. Check if you outperformed Bitcoin every year. Because if you didn't, then you merely wasted your time and probably shortened your life-span from the mental stress and loss of sleep.
Day trading is not an easy thing this is difficult to do maybe you will be depressed because of lack of sleep or drain the mind, then I can't afford this then it's better to invest much more relaxed do not have to think about anything.
The daily or short-term success rate in 1 year then it will be more minus, if I myself do it.
The success rate of investing for 1 year in Bitcoin then the success rate is high, not even a loss if you don't sell it.
