Before investing, evaluate the risk. All coins fall and it is normal and healthy. A currency that does not rise or fall cannot be considered a short and medium term investment.
We all want to see quick profits in a short time. But what do we do when an investment starts to fall? Our prudence and resistance to loss are tested. A prior evaluation before investing is necessary.
In my opinion, a 10% loss can be considered an acceptable loss. But what if it goes down more? Withdrawing your investment when the value of the currency falls will only lead to losses. Unless it is to go for a better investment you will only lose your money.
But as the saying goes, everything that goes up must come down and everything that goes down must go up. Although it is difficult, sometimes you have to recognize a loss, but other times you have to stay. How to know? Own criterion.
Personal work and dedication.
