I prefer you both of them, for me now i separated my accounts in to two one for day trading and the other hand is for long term purposes with solid fundamental coins like bitcoin, ethereum, litecoin and ripple, these account intended with long term method. While the other account for day trader i have their a cheap coins and other coins for pump and dump purposes. Yes it is too stressful and risky, you need to focus on day trading or else you may lost you're capital. Unlike long term holding lower risk than day trading all you have to do is wait for the time when you need to harvest them.
