I think they are wrong in this case.
The guy doesn't stop talking about gold, and nobody says bitcoins are going to compete directly with gold or even other fiat money. Bitcoin will be successful ONLY just by taking away a part of paypal's and Visa markets. Those are their competitors and only with that its future is guaranteed as an exchange medium for some type of transactions. That might help stabilizing its price and allowing it use as the "digital poor's man value keeper".
How the hell are you believing that bitcoins will ever compete with Visa or paypal when the fees are like:
- 0 for Visa
- 25 cents for paypal
-
1 million time the amount you're sending when you're sending 0.0000001 btc
If you're accepting Visa and the fee is 0, you should become a merchant account/gateway provider because everywhere else in the world charges 2-3% + US$0.15-0.30+ per transaction not including the risk and fees from chargeback.
