I would not recommend day trading unless you have a software to do it, or have a really big capital. It's just not worth the time and effort personally. Also, with fees for each trade, I don't see it being as profitable as just holding onto the coin long term. Highly unpredictable and requires a ton of luck and knowledge for it to be successful. I'd stay with investing.
If you have big capital, the best thing to even do is to trade based on signals and trends. Following trends has really helped me personally to get a lot of profit and then make good trades. I do not fancy day trading, whether you have big money or not as that is a lot to take in and your big wallet is not even going to save you with the level of market volatility.
