I used to invest in ISO and make a profit. Recently, a lot of coins in which I invested fall down after entering the stock exchange. I do not know what to do about it ...
You have 2 obvious options at the moment. The first one is to sell your coins at the actual price on the crypto exchanges right now and be not very happy because of the low price. And the second option is to wait for the bull run and pump of your altcoins. But no one knows when it will happen. In my point of view it will be in the second half of this year or in 2020.
