Emotions do play an important role in trading and investing. Fluctuating prices affect psychology and I think if we don't have a good trading and investment plan, we can panic and sell our tokens at low prices.
But if we have a good trading plan and invest for the long term, I think we will get profit as long as we hold the tokens.
Holding tokens does give us more profit potential if we wait patiently for a long time, but the risks and frustrations will be the worst. You don't know how the scenario will last, sometimes your assets go down so much and in fact my experience with my old tokens was really bad. The score is zero this time, just because of the wrong mindset without further updates from the project community.
