I also don't wanna exaggerate their success but it's also good to see a young project achieve such success in a short period of time.
Good thing that you know or admit it that it was a kind of exaggeration, because it was indeed one. A true success doesn't have a shortcut and will only be achieved in a long period of time. In case you ever see one who did for the short term, expect that they will still fail and it can also happen very quickly. I think you can only say that, because you lack in patience and you want to earn an easy money.
Only if it is longevity is tested and it's doing well - then it can be successful, I too think so.
A pump in popularity or in price is nothing if it's not bound to real use cases and the community that is ready to be active and to use the final product, pouring their funds and efforts into it.
