Store them yourself and spend them at shops you trust. What is the problem?
Here is a quick and dirty method to avoid getting scammed: Only spend your coins at shops that have existed longer than Bitcoin (have a business model that functions without Bitcoin).

Really Holiday, really. And what if I want cash? Can you point me to the Bitcoin exchange that's been here since before Bitcoin?
