So on what is your decision to buy BTC based? On the stories they tell? The greed? The first thing a crook needs is a good (sales) story. So good stories are not always reliable.
This is the basic difference between the BTC buyers and the guys putting full faith and trust in aircraft carriers. It is a simple matter of hedging our asset base against the world debt bubble that increases by the day and can not ever be paid back and supported by an interest rate reverse bubble of near zero. BTC is already established worldwide and it has no upward limit (no sales projections, PE ratios, etc.) It is simply supply and demand and the supply is known. The possibility of a world economic meltdown is real and that is why BTC has risen from a few cents to 7K already and it has just scratched the surface of world penetration.
