Just buy some eth or btc and send them to your account at bittrex and start buy and sell all alt coins, or just buy bitbay.
I prefer to start buy eth, its just soooo much faster transfer (btc suck at transfer). But then u would have to sell them for btc and then buy bitbay.
yeah find some coins with easy transaction period then sell it out to btc before buying either nem, xrp, ltc or eth those coins are still pumping and dumping so better to make a good timing to earn from the fluctuations, good to hold and wait for the value to reach your target goal.
