all must analyze what coins are held. whether it has the potential to rise in the long term or not.
if misaligned and left behind the information then hold the coins will be useless.
Of course, what is even the point of being an investor and not monitoring the situation of the coin or token you are holding ? The market will not always be in a position for a long time and there would always be time for correction, so in that case, it makes lot more sense, to use those periods of peaks to sell, buy back at dips and you stand to gain a better position in the long run. Holding though is safer without trading knowledge, but to me not the smartest thing to do as an investor.
The difficult part is choosing the right coins/tokens to hold for short or long holding. It needs an extensive study of the coins/tokens and the market.
That is where all the tricks and knowledge matter a lot. All coins are not good for holding. Hence filtering out the improper things will do all the needed jobs. People learn these tricks slowly. I guess in near future scams may get eliminated when most people ignore them.
Then you are a trader. A fundamentalist wont know how to sell and buy dips, you need trading experience for that and technical analysis. If you bought ''dips'' when bitcoin was crashing from 20k you would be broke right now. You are either someone who holds for a long time, 1+ years or you are a trader who sells and buys every few weeks. Also called swing trader.
