Trading not bad though but I will say you're making the right choice avoiding it ( trading) , because trading not something one can start without having good knowledge on how it works and stuff because to understand trading takes time and energy, and also determination, without any knowledge you will only get yourself rekt (losing everything).
you right though, if you looking for relative peace of mind and a sustainable Growth
Then investment is the goal not trading.
Yeah, there are People that makes it big from trading but who trades with something as Valuable as Bitcoin?
Even with a perfect technical analysis
Failure would still exist in trading.
Investment just require consistency, a dedicated mind and Risk management.
If trading was so successful, wouldn't be the face of Bitcoin.
