Actually day trading is very risky but if someone can understand how it works, it's easy to make money through it. In any case for day trading one must first be able to predict which direction the market will take place especially in the short term and also someone must make liquidity high enough to cover the amount that one wants to enter without interfering with the price. When the market is stable, it is an opportunity for someone to invest for the long term but it is not profitable for daily traders.
