Day trading can be profitable and not profitable to any individual that wants to be making money from doing it but they have to make sure they know how to trade very well before they start doing it. Many individual just start trading without having any experience and that's why they always fail and begin to blame the market of been a scam meanwhile they were the ones that didn't understand what they were doing but because they were winning they thought they're good traders.
When you start trading, you can get beginners luck but we don't have to let that confused us because the more we go dipper the harder it begins to get and we start losing so it's always wise we know how to trade properly before we decide to be doing it everyday for profits.
That's mostly the case with new investors, those who have heard from others that cryptocurrency is very profitable and one can easily earn a lot of money, and they never did any research of their own to understand how things work and whether there is risk involved or not but they get in the market and start buying cryptocurrencies without any prior knowledge and with zero experience. Some might get a newbie's luck but that doesn't happen with everyone.
So, a person who is just about to enter the market needs to at least do their own research to understand the market first and they should only start buying once they realize that they now have enough knowledge about the market and they won't just waste their money by investing on useless coins.
