Train will remain alive and well until the next official hardware announcement... then we'll all be bitching about not buyiing enough shares under BTC6.
Agreed, we've had several stops on this train ride already:
0.5 XBT/share
0.7 XBT/share
1.2 XBT/share
2.5 XBT/share
4.5 XBT/share
Double digits
will happen in 2013.
Double digits would entail ASICMiner shares making up 30% of all bitcoins ever mined. Do you really believe ASICMiner is worth that much?
