Yes day trading definitely works. Many investors do that, but day trading is very tough. Day traders need to have a lot of knowledge. They need to keep up on the latest stock market news and events that affect stocks. The process requires a trader to track the markets and spot opportunities, which can arise any time during trading hours. Dont consider it if you have limited hours to spare. Moreover as the crypto market is a 24 x 7 market it requires you to keep constant watch over the market everytime which can be stressful at times.
