Whenever the price tumbles you will see a few despondent people on this forum talking about how they want to quit BTC. Often the response they get is almost one of encouragement. E.g. "Good more cheap coins for us" or "Let's get rid of the weak hands".
I don't think this is how we should always be responding. It's not good when people feel bad about how things are going. We need adopters, not disillusioned quitters.
