To be honest, if you are optimistic about a coin, the right thing to do is to comment or like it on Twitter, and to liven up the community atmosphere when it drops.

If you think it is not good and you are not optimistic, just sell it, and then go out and say that the drop is numb instead of holding it and being negative.

Because your coin is your money, it is possible that others will sell it because of your words, and your coin will drop more
