It is not the patience that triggers panic selling. It is the lack of knowledge on what it is their holding. Lack knowledge meand lack of faith, and lack of faith means easily get shaken when dumps occurs, may it valid or fake dump. So the first move this people who lack faith is to sell their holdings the soonest the can.
Without patience in trade, there is nothing to do, because these can only create yourself the additional stress and loss of funds.
And a lot of factors need to be considered before try to take a long-term decision.
I think some coin will not worth to be longterm investment especially like EDR and something like that's just a scam coin.
