Do not spend your Bitcoins. Not now.
So when? After it reaches some value!
Most people not spending their bitcoins anyway but they should spend if there is possibility for them to spend then only the adoption happens if everyone thins bitcoin should not be spend then this fact will stuck forever which could ruin the intention of system at some point.
First of all, if Bitcoin is not being spent do you think that the price would move up to this state? Even if there are miners who already existed it is still not enough to move the price of Bitcoin. The supply and demand are the ones that making the price moves and that is the start of adoption since people started to discover it, as more and more merchants are accepting Bitcoin.
