I'd have to disagree. Probably going to see eBay drop below $50 before the week is out. I just don't see this going to $75 anytime soon. The build-up last year from $30 to over $50 was smoke and mirrors based on skewed mobile figures and increased fees on sellers, namely fees charged on the shipping portion of a transaction. As for mobile users, eBay likes to tout the numbers as new customers. It's not, it's people accessing the web via phone or tablet instead of their desktop PC.
Not to mention, Paypal is about to face a slew of challengers for online payment as well as mobile payments. In fact, one of the founders of Paypal has launched the mobile payments company Affirm.
