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?
There could be many reasons for the price to go down after listing.
- Don't have real product or service - ICO succeeded due to HYPE
- Fake promises months after months - investors start to dump
- owners dumping and so on.
And sometimes the project is good, but the promises they made come too late that investors/supporters lose their patience.
