I think your are wrong, not all day traders always lose money, I know day trading is kind of risky, you should be a professional trader before you can be a day trader, because it's involves doing some technical analysis before buying a coin, but lot's of people still make money from it. We all know you can't be making profits always their will definitely be lost sometimes but you won't lose your money completely and your profit should always be more than your lost. If you don't really know much about trading then it's better you avoid day trading, if you don't know much about trading is just better you buy and hold, HOLDING those not require serious technical analysis, just buy and hold for long term, also if you are investing always make sure you invest in bitcoin to be at a safer side.
