Once that they get listed on the exchange, the dev team is going to dump their coins for sure, i can see it coming, just like it always will happen to all those newbie icos who their devs have no history about ico's, or ipo's. It is a waste of time and money, and it envolves a lot of risk, i dont suggest anyone to join in there.
You hit the nail right on the head. Sadly but true, this is just the way so many ICO's are being conducted nowadays. Its a pity for the investors that are not aware of this and just naively put their hard earned money in these ICO's, while some lazy people get rich off their backs. Its a shame. I hope that there will be mechanism to overcome this kind of schemes in the near future.
