I think this is a Yes and No question. It is yes because some projects have flourish in the past with the help of advisors and it is NO because some advisor are not relevant to some project and they only receive coin without contributing any meaningful thing to the project. This issue of adviser depend largely on the choice of the project management itself. If wrong advisors were chosen then they won't help the project buy if the right ones were chosen then it will make the project flourish.
