So far I have not done anything with my altcoins, they are lying on my wallet and that's all. To sell them now there is no sense, because the price for them and so below is nowhere, and in general the market sank and everything costs, let's say, inexpensively. Because they are still on their wallet and are waiting for their time. They will rise in price, then I will look and think about what to do with them. But I do not really recommend selling now.
This is what I think too. There is nothing that I would be able to do if the prices of the coin dumps other than just waiting it out. If the price does not go up there would be no need for me to sell seeing as I would be selling at a loss which will affect me. Before I invested in my altcoins I knew there was a possibility that the prices would dump.
