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 ...
If the general sentiment is bad, then even good projects can fall upon exchange listing. I have noted that 99% of the coins are getting listed at a discount to their ICO prices. This can be due to two additional reasons as well. If the coin is over-priced, then it is bound to flop even if the project fundamentals are good. And secondly, if the promoters dump their coins, then the prices can easily crash up to 90% in a single day.
