I think everyone will say the same thing, namely holding it when the market falls and sells it when the market goes up. But, I think when the falling market is a good time to buy a few coins that have the opportunity to increase and when the market falls I will hold the coin that I have and observe the market development from day to day, if some coins do not allow me to recover will sell it to cut bigger losses.
Definitely everyone will go with the Same if the market goes down hodl it, if the market starts recovering sell it that's the mantra of trading. In my opinion time and patience plays a key role here.
