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.]
