Investing short-term means exposing yourself to more risk, because you will never achieve success from this investment and never reach your goals. Even if you buy a little bit of Bitcoin, if the investment is for a long time, the portfolio will be much bigger. An Austrian Bitcoiner says that investing in Bitcoin for a long time i.e. 10 years using the DCA method will change your life i.e. Bitcoin will change your life.
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.
