The important thing is we must know what strategy do we use, because it can tell us when we sell of our altcoin
example we do long term trade with MA indicator, then set 200MA, if price break up MA then buy, break down MA then sell
that's just little example of how we use stragey with indicator to know when we sell
It`s easy to say, the best moment for selling assets is at their top! After that price usually drops and you can
think about buying again and have your asset again and some profit plus.
But where is the top? It`s dilemma for every short-term trader. It`s one of the reasons I don`t like to speculate,
my timing is always wrong. My goal is future, and I invest in long-term. I will not sell even if price goes very low,
I will think about buying more if I still have faith in the project.
