I can't really see any crypto currency being an efficient source of income. The price fluctuates way to much. One day you could have 50,000$ in a certain coin and the next day you're flat broke and can't pay bills. Of course it would work if you were very, very good at predicting the price of the coin so you can exchange when you feel the price way going down, or get more Bitcoin when you think it is going to go up, but you'd already most likely be in luck for a stable job if you were good enough at that.

You get the idea that yes, Bitcoin fluctuates way too much. The Biggest argument for Bitcoins is also the biggest weakness, in that is there is no regulation of the currency. So if the Currency value increases or decreases, there is no agency who is gonna cut intrest rates, pump capital or stop production to keep the value floating. Its one day sink, or one day swim. Its gonna be like life in the 1800s. One day youre rich, one day you are gonna go broke, until they made the Federal reserve to start currency regulation and stop there cyclic panics that were happening. But Bitcoins are designed specifically to evade regulations, so I dont see this happening anytime soon.
