I think some investors didnt see yet the full potential of this ICO , maybe because of the lack of updates here in this forum , but If they see that the people behind this project is active then Im really sure they will take time to invest in this ICO since this project is one of the good project.
Maybe, other investors are hesitant in investing in this project (boosteroid), because of its offered services. I mean, the leading companies are offering the service in a much higher price than boosteroid, maybe they just cannot believe that boosteroid can offer the same service with a cost that is unbelievably lower than those of the leading campanies.
I have read somewhere in their paper or in this thread, that they chose a place where the cost of electricity is low, and around 80 percent of their services is requiring electricity and that is the main reason why they got such lower price. Maybe if the investors can read that statement then they won't as hesistant. If they have read about that but still doubt, then its their loss, while boosteroid users are enjoying their services, these doubtful people are still paying for their old services with a very high price.
