Daytrading is more fun than just HODLing. You will get more knowledge about cryptoworld when you trading, but you get nothing when you hodling.
it depends are you goingfor small to large sized investors, everyone will say something similar to holding because day trading is very risky compared to holding.
Day trading is profitable sometimes but could prove extremely dangerous when markets move against us due to some false decisions but that is only when you intend to sell them the same day or in the very near future, but if you intend to wait very long just the way many did with Bitcoins, then returns will be overwhelming.if you have big investment then you can also do short term trading through which you can make reason able profit.
Definitely, it depends how you balance your trading. You may do day trading and proceed also in hodling a coin that you have for a long term investment. Both is profitable you can do as long you know how manage your activities and decision making.
