Even if 1 trade is made, that does not give it a real value. If that trade is made, that doesn't mean the price on the exchanges is just going to shoot up either. It's only a real value if it can maintain that price. Just because I can sell $30 watch to a naive person for $350 does not make it's value $350. It's still high speculation. Doesn't mean I won't keep my eye on it, but I'm speculative. And unfortunately I have real work to do, time to close the BCT.org.
That's not really a fair comparison as they are a delivering a product worth $300 which is currently trading at $6 so it would confirm they legitimately mean business and are willing to bear the risk. If you know you can get something worth $300 for $6, $50 or $250 there will be new buyers who actually want to use the product and if they can get it at a discount they will buy.
