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 ...
I think i would be disagree with the way of think that listing is the deciding factor for a coins to be died.
In my opinion, the main reason would be because there are so many issues about a coins that makes the coin holder to get worried and end up selling their coins in a cheaper price.
