Be smart and always take advantage of any project that brings you profit, do not stare at your wallet and say "I'm going to be rich in 3 years later," this is a 1 percent out of 100 percent chance that it will ever happen, remember, being rich isn't the most important part of our lives but living is, and remember, being rich isn't the most important part of our lives but living is.
every form of investment we must have a purpose, because with the goals we have it will make it easier for us to run everything. and in crypto holding altcoins for a period of up to 3 years I think it's ridiculous. because we all know that cryptocurrencies have an erratic market trend. so we have to know when is the right time to sell and the right time to buy it back, so that the profits we get will be greater than if we hold altcoins for 3 years.
Purpose alone isn't enough for an investment ot be profitable. One must do a full research of the investment so that he can calculate and manage the risk involve in the said investment. We should also know when to buy and when to sell else we might end up buying high and selling low and that is devastating to our portfolio and funds.
