I used to get worked up over a loss in cryptocurrency not until I realized that these losses can be mitigated using the right investment strategy.
Investing and holding a coin is not the issue here, the issue is knowing when to sell.
The most successful investors are those who know when exactly to sell.
And to do that, one need doses of patience so as not to fomo and sell at loss.
The difference between the rich and the poor is simply the ability to know the right time to sell.
I think there is another important think than knowing when to sell a coins, but also when to the right time to purchase them. Since there are many people choosing the wrong time when purchasing coin and they ended up loosing because the price dropping after they purchase the coins.
