Indeed, everything is just fine. The blockchain transaction volume in USD (minus changebacks) has peaked over the last month, and is almost back to the June 15 level:

Like the traffic on the "BipPay.com wallet", whose plots I posted recently, this chart does not support the claim that use of bitcoin for payments is increasing. That use may be increasing, but most of the blockchain traffic seems to be non-payment transactions, so we would not be able to see the increase anyway.
Moreover the current level of blockchain traffic is very easy to fake, and there are many people out there who would be motivated to fake it.
