By definition Bitcoin is money and it already is store of value and you can use it to create passive income for yourself. But to do that you'll have to invest that "money" into a real business that generates you passive income. That business can be your own (eg. imagine you are running an exchange) or it could be invested into someone else's business assuming you accept the risks that it will have (like investing in a casino like freebitco.in that used to be safe and gave a decent return, it no longer is safe though).

The point is these two characteristics are complementary not contradictory.
