And they sell like hotcakes!  People buy bottled water, people are not rational.  These things are cool, people want them, and they will pay for them.  As long as that happens I am a happy investor.

And WHO is to say these wont/can't pay for themselves?  We know little to nothing about their lifespan, the estimates on future transaction fees are impossible to make, although difficulty is climbing, it may go down... maybe people hop onto some ALT Coin in mass.   Maybe an asteroid hits china?

Either way, I imagine the price of 1btc each, even with the recent USD/BTC events, is far above cost.  We can afford to drop the price more, and sell more... at a profit.
