How about rational self-interest? That often has a calming effect on people, as it renders life so much more simple. What I mean is, you are wasting your time relentlessly knocking the coin and engaging in these pointless interchanges, the negativity and the agitation. You don't like Blackcoin? Fine, move on. Why give any more time, thought, or emotion to the subject? Don't you have a life? Don't you have more important things to do?
