Once used and accepted by the masses, who is gonna try Bitcoin?
Hmmm let me guess. Everyone like me who don't use facebook?
It doesn't change the fact that bitcoin is scarce and is subject to gain value over time compared to fiat anyway.
Any mobile payment vehicle which becomes mainstream instead of Bitcoin, prevents Bitcoin from its full potential value. When the masses use Facebook mobile payments, Bitcoin might remain geek money. It will still increase in value over time, but far less compared to when Bitcoin goes truly global.
Facebook already has over a billion users!
how is fb payments any different or improved compared to paypal- nothing evolutionary OR revolutionary. bitcoin will still have ALL the actual advantages
