Is there any actual value or in mining using the primecoin method when compared to sha256? Is it a superior mining protocol?
Well it might be more complicated to make pools for it, since breaking up the work into small pieces might not be as simple as it is for hashcash.
Whether that makes it better or not depends maybe on whether you are pro pool or prefer there be no pools due to pools being dangerous concentrations of power.
