Day trading can be a very profitable method to make a fast and big money, but it requires a lot of knowledge and experience in trading as it's much risker than long term trading, which is safer, compared to this modality.
Pretty Riskier method of trading, I don't usually prefer this method as even sometimes the most knowledgeable people even can't make profit at the end of the day. Crypto Market is too unpredictable and analyzing it correctly every time is nearly impossible. Day trading in other sectors are still in better position in terms of risk.
