I hate any links to Wall Street Journal. We can't read it unless we pay for a subscription. Can someone copy the relevant part of the article and post it on here?
Anyways, as of now I don't think crypto currency is anywhere near being a direct competitor of paypal. Sure we have a sizable volume, but it's mostly used to trade, not buy goods and services yet. Paypal is a payment processor, and I think it's quite a long ways until bitcoin overtakes paypal market. People have to get off the idea of using it as an investment vehicle, and see it more as a currency before it can be accepted by the average Joe.
You can copy the headline, paste in google and get a ton of other sites that have the whole thing, or at least the point of it.
