After reading this, I will not invest any penny in them.
We’ve decided to spread out the sale over a longer period of time (five years), so that instead of selling almost 11B tokens in one go this October, we’re going to limit it to 1B tokens each year, for nearly five years. In addition, we reserve the right to burn further tokens if we decide they’re not required at the end of 2018 and each subsequent year.
They will be making several rounds of ICO for next 5 years
It seems they don't have any stable long term plan..
