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 ...
Investors hold and bounty hunters sell and there are post ICO investors who are waiting bounty hunters to dump on 10-100X lower price and then they invest.
You can't do anything about it, investors should know that nothing comes over night and you will have to wait long time before make profit. Look at how market looks at the moment, don't expect too much.
