yes I agree with you I also always give a target when I will sell my coins. when the coins that I hold have experienced a 50% increase then I will sell them. if after selling the price of the coin goes up again I will not regret it because I already made a profit. but if I continue to hold the coin too long without a target and keep hoping the coin will rise again. I will be disappointed when the coins go down because they do not get profits because expectations do not match reality.
This is another lesson I want to employ. I learned it the hard way because I have some coin at has no value at all now. This is a piece of sound advice especially if you are starting on cryptocurrency especially on altcoins or tokens. Don't hold for too long especially the project is new and just launch, big whales will dump their holdings as long as they have profit.
