Also, there other big players in this game who haven't said a word about 2x;
Bitmex, Bitfinex, Bittrex, HitBTC, Poloniex, Gdax, Bitstamp. > Their 24hr volume for today is 253.266 BTC(combined).
This exchanges will also play big part in November. They usually talk and decide together. So we'll see how thing will roll at November.
One clarification to be made here: GDAX and Bitflyer are part of the New York Agreement. If you weren't aware, GDAX = Coinbase (the former is their order book exchange interface, the latter is their simplified broker interface). GDAX is the largest US exchange on the market. Bitflyer is the largest Japanese exchange on the market, and fluctuates within the Top 3 exchanges in the world for volume.
That's not an endorsement of 2X by me. I'm just saying that we can't act like major exchanges "haven't said a word about 2X." Shapeshift and several major wallet services like Blockchain, Jaxx and Xapo are also signed onto the deal. That's nothing to sneeze at!
