A steady income from bitcoin untu now is
1.Trading
2.Faucet
3.SIgcamp (in this forum)
I think all three can give every day our income, other than it was a gamble but it could not count on because it is not every time we win a bet
I do not think that it would be easy to make a fixed income with trading. Well, trading is more likely to make an income that is not fixed, because we never know whether we really can predict the price or not. but I believe with the faucet, and signature campaign, we can make a fixed income, although for a short time.
