also, dont but BTC on coinbase and send it to whatever exchange you want. The BTC network fees are out of fuckin control and take too long. Im not telling you what to do but ill tell you what i do. I buy Litecoin on coinbase, send it to whatever exchange for about 25cents, then sell it for BTC once its on the exchange and pay the small comission as opposed to the BTC network fees. I save about 85 to 90% in fees by doing it that way. try it once and see how much you save. it only takes one extra step
