There are plenty of bitcoin exchanges in Europe (bitstamp, btc-e, HitBit, cryptonit, nextcoin, ...) and Asia (itBit, Bitfinex, ANX, ...).
But what are the main U.S. based bitcoin exchanges besides kraken and coinsetter?
(And coinsetter seems to mainly duplicate bitstamp orders ...)
We'd like to add more north and south american bitcoin exchanges to our realtime aggregated bitcoin orderbook and order them by best price.
