So what would we do? Prepare to sell all altcoins to make a big dumping or continues hold? you say what we have known, but if we invest we must accept to lose.
In my opinion, I continue, because I personally have invested, I am ready to accept risks and losses, I do not expect predictions, but I continue to do research, I wait until prices really rise.
Each investor chooses to continue to hold their coins or sell them now, it depends largely on the prospects of the coins that you have.
