There is no guarantee that a project can reach a minimum of 10x after 6 months, it depends on many factors that I think most of us already know.
MFX too, declaring 10x - 100x after 6 months is overly optimistic and unrealistic. They need to work diligently for the MFX before dreaming about its value.
The best ICO project I participated in in November 2017 and until now over the past 13 months it was just difficult to reach 3x.
