It depends on your situation and urgency. If you are well-off, you would not see much of an urgency to acquire more BTC, because they can already afford everything with USD. Instead of seeing BTC as sound money, they have it in the back of their mind as a speculative investment, so there is some resistance to change in that way.

If your economy is weak however, you'll want to store more BTC early on. The most knowledgeable person I know about Bitcoin told me, "You get Bitcoin at the price you deserve."
