It's complicated to earn steady income from bitcoins as price fluctuations will never help you in reaching there, to make it really steady.
price doesn't matter that much. the main problem is there is no any good and long term job..
if you earn a good amount of bitcoin then the small price drop won't affect your earning..
like if you earn 1BTC a month. and bitcoin price is 600$. if it drop to 590$ then there no any big deal/difference...
