As a rule, most blockchain- projects that have collected tens of millions of dollars for ICO, issue tokens on the exchange without real production growth.
What does it mean?
Well, you're still new to the thing. That's how it used to be for most of the ICO. You should ask yourself why investors are now fond of selling their tokens once the ICO sales is over. That's because they want to be holding shit coins. People only go for it at first and they are being hyped to the extent they will grow during the ICO but after the ICO the price will start falling and if you continue holding those coins you will just end up as the loser there cause hardly will anyone buy those coins and they are going to keep falling. So it's up to you whether you want to start doing the same thing like others do, or just stay off from them completely.
