@eirexpat is correct and further to what he said, the oppies would be a good buy if the sp rose to .004c and the oppies stayed at .001c. That way you could buy 4 times as many for the same price and if the sp keeps rising the oppies SHOULD rise in a similar manner giving you higher % returns on the money initially invested. However the oppies are much riskier if the sp doesn't rise. DYOR and this is just my point of view. Hope it helps
