I personally am a hodler. As you already said, you need to invest a lot of time and effort in order to be a successful crypto day trader and i just don't have the time for that because i am working a full time job and we are also currently remodeling our house so it have almost no free time to do research or to follow trading channels and so on. I am also a very careful crypto investor i would say, so doing active day trading is just not my type of thing i would guess.
I also think that if you start to trade actively you should only use money that you really can afford to use because especially when you have no experience at all the chance that you will lose all of your funds are pretty high.
