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 ...
Most likely this is due to the fact that before all cryptocurrencies showed growth. Now, only a few are able to withstand competition and a lack of interest from investors.
They all need publicity, because without that, the coin might suffer lack of volume, which in real sense, will not bring good liquidity to its investors.
Well, it is all about time, which will definitely be overcome.
