"5/ Only 10 exchanges have >$1M real daily bitcoin trade volume. @binance, @bitfinex, @krakenfx, @Bitstamp, @coinbase, @bitFlyerUSA, @Gemini, @itBit, @BittrexExchange, @Poloniex / @circlepay You can see the daily BTC trade volume on these exchanges at: http://www.bitcointradevolume.com "

Yeah. Subjectively (and this is with a U.S. bias), I would've ranked them as Binance, Coinbase, Bitstamp, Gemini, Bitfinex, Bittrex, Kraken, Poloniex, Bitflyer, Circle, ItBit.

[Now I'm going to peek at the actual volume rankings. Hmm, not bad - Kraken is doing better than I thought, and I underweighted Bitfinex and Bitflyer per U.S. bias, but it's otherwise quite close.]

Those match my extremely anecdotal observations in this arena.
