So if I understand correctly, the volume is even more abyssal than we think? 
Wouldn't services like Bitpay use some darkpools?

It is certainly interesting. I think since BTC isn't only a stock/currency/protocol/technology/commodity/etc. we might be witnessing something oddly new - just a balancing, so to speak of current demand coupled with a bit of uncertainty. I'm sure there is lots of money on the side waiting for BTC to jump up (and then they will ride that wave) or waiting for BTC to crash (and then they will try to pick-up "cheap" BTC's).
Looking at all the incredible topics at the conference (via the articles on the bitcoinchannel.com) I'm really struck by something:
This isn't just about BTC. We are entering a technological/protocol of an era that is game changing. AND very little of it is about making money with BTC. It is about:
decentralizing DNS
creating decentralized means of voting
tracking or "ledging" stock transactions/ownership (and government, etc.!)
decentralized electronic markets
more cryptocurrencies
decentralized exchanges
TONS of decentralized services - every governments worst nightmare, but inevitable.

(The cat is out of the bag and the bag is no where to be found.)
And of note here, the only real "coming down" on us by the government has been to follow FinCen regulations... UM OK!
And just from an "end user" perspective (ha ha), what this amounts to is anybodies guess, but it sends chills down my spine more and more the deeper I get into it.
I pulled some of the ideas above from this article, really a brilliant and mind opening read. http://reason.com/archives/2013/05/20/the-top-3-things-i-learned-at-the-bitcoi
This Black Swan is really a Black Swan within a Black Swan (and all participants are anti-fragile) - see my sig for definition clarification
Got off tangent there, welcome to BTC
