you need to do more tweets every day . And better do do it at platform TVE . a lot of people are using it now .
But too late to use it, since the ICO will end in 8 days. They should do it at the first time that twitter bounty is started
This should have been done at the start and a good marketing would have helped to reach the minimum target easily, but anyways there are still 8 more days to go and hope the project reaches the minimum goal.
