I'm interested to hear what people find to be the best exchanges.

Inparticularly I'm interested in exchanges with a wide array of margin pairings.

I'm in the United States so Bitfinex is sadly off limits to me.

Poloniex is ok but they don't allow bitcoin margins, only a few altcoins.

So let's hear it, anybody have exchange reccomendations?



Kraken, Poloniex, Bittrex, Gemini, Gdax, Cryptopia, Livecoin, yobit, coinexchange.io, bitstamp, where else?
