It's very hard to make a living trading bitcoin unless you have a lot of it already.  Also, it's easy to lose money on scams and failed exchanges like Cryptsy.  I lost a lot of money on that exchange when it folded.  I was just starting to figure out how to make a small profit. Only ALTS have great return by investing in them! You can trade whole year BTC/$ on BTC e and you'll never get more then 10% per day if you are lucky. But with alts you can achieve that multiple times and more. And after all everything is risk!
