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 ...
It is not the listing in exchange causes the coins to drop its value but the bear season that affect the entire crypto coins are the one killing the price. Lack of investors interest in buying new coins since majority are focussing in top coins. For now avoid joining in ICO just be patience everything will br ok once market become bullish
