decentralise. do it now.

Actually the majority of Bitcoin trade has happened OTC since forever. In 2011, in 2012, in 2013. That a majority of Bitcoin's periphery (ie, people interested ideally but not invested significantly) don't know about this is neither surprising nor terribly relevant.
Out of curiosity, how do you reliably measure the amount of bitcoin exchange going on OTC?
