It depends on your style. Day trading, as well as middle-term and long-term trading patterns, is cool if you know how to do it. Now the market is volatile and going down but its nothing for day traders. Various altcoins may change price rapidly during the day, so its really possible to benefit from the day trading. Just think about the risks first because they are significantly higher during a short-term process. Be ready for losses and try to diversify your portfolio. Also, consider combining day trades with long-term ones.
