since the start of 2021 the price of tokens have gone have breaking statistics, altcoins take an all-time high, and we are very happy all these things turn into a nightmare in a single day, almost all of my friends never touch their coin hoping they would reach another all-time high, the same thing that happens in 2017, now the market almost wipe all of our portfolios, what's the lesson of this, when there is a chance to take profit, take it, small or big, it's again, I saw some posting they earn millions, they are so happy, but after a day they regret it, why because they are so ambitious, and no contentment on what they have, always take gains, don't let it slip away or you'll regret it.
Regrets normally occurs when we failed to take chances in times of opportunity, so what we need to do in order to prevent certain emotions that could affect our decision making we should learn to have satisfaction. If we don't have such strong principles we can't move on and continue our journey in taking profit. Once you owned good coins, don't deal with you can't afford to lose the risk behind.
