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.
Emotions can have both positive and negative sides. but the most important thing is how we manage these emotions, lest we be influenced by emotions. so in my opinion prepare trading risk management before we trade and invest. This can minimize the risk of loss due to being trapped in the wrong emotional position
