I do not think you should rely too heavily on mining results, try to make other alternatives to get additional support. Such as investing or can also follow the bounty program.
Mining is currently no profitable at all, with high electricity cost, more and more miners, low price. You cant even breakdown your operational cost
So I will stay away from mining as of now. Bounty is nice but it doesnt give you much like it did before because too many participants.
Trading and investing need to be considered
It is possible to make a living in bitcoin. Actually, it can give you the life that you deserve when you are patient and willing to risk for it. There are many living proof that bitcoin changed their lives because of bitcoin. You can invest what you are willing to lose because bitcoin value is changing at an instant. But if bitcoin will eventually go up quick and you have a enough bitcoin, you are very lucky.
