It depends on the advertising plans. If the clickthrough's create demand then that should be enough. If the advertising plans are not done, then something else needs to create demand like a high stake %. High stake % has its pros and cons though.
We have had no answer about the advertisement plans and if they are still valid if they are then the 8% annual will be ok, but if they are not i agree it needs something else like the high stake and then you take the good with the bad but atleast the coin will have buyers.
