The lower the price, the greater in difference of total coins you can purchase.. as price increases again it becomes more difficult to double up.. pretty basic, but most people overlook the basics at times. I suspect it will continue to go in the longterm as well. There were many who made a bunch from the cheap days.. and there are many stocking up now (will someday be considered the cheap days as well?), as the coins "change hands" ... as they say.
