Right, but how many people really trust Bitcoin? And by trust, I mean trust that it will retain its value for the foreseeable future.
I have trust that the Euro will retain its value, so I feel confident pricing my product and services using it. On the other hand you'd be crazy to price anything in Bitcoin.
No one has trust in Bitcoin as a currency. Some people have some degree of trust in it as an investment vehicle, which is fine. That doesn't make Bitcoin a currency any more than gold is.
