After a while here in the forum I read a lot of members worrying about there crypto investment/trade. I would rather choose a stable and highly trustworthy altcoins to invest for the long time rather than chasing those coins thru trading. I find it super stressful to read those people losing large amount of their hard earn money.
There is no such thing as stress free investment.
Stress free is when you invest the money which you can afford to lose .
Also often stress becomes bigger in situation where potential gain and lose is bigger.
Basically one should chose between stress level and potential profit.
