I know that if your pushing at least 40 THS of mining power right now you can make 1.0196 every 24 hours. This is taking into account electricity costs etc but not luck nor price of the initial mining equipment. If you want to make 1 BTC a day, you can either become a crypto day trader, though making a significant amount daily will require utilizing a Trading Bot, you can work some successful marketing campaigns for other big name sites that have affiliate programs(Easiest route if you have experience in advertising, SEO or Running Advertising Campaigns), many people I know currently have been making a fortune daily simply buying Ghash's from cex.io for users in japan and china and taking their payments via paypal, many people also do big referral campaigns for in the cloud mining providers like cex so for example from every user you refer, you get 3% hashing power based on how many Ghs they have purchased, you can also sell voucher codes from cex.io on ebay and make a decent amount.
If you want to try In the Cloud mining I would stay away from CEX.io(they charge 26 cents per ghs, too much imho) and check out Zencloud from Gawminers(the folks in my signature) or other alternatives and make sure that you are purchasing enough hashing power to make ROI on your initial investment(also check out what people on the forums are saying about any other ITC mining providers as some are not good at all or scams.). Simply Google Bitcoin profitability calculator and you will find numerous tools to help you determine roughly how much you will make depending on hashing power, electricity costs, initial hardware pay and more. If you intend on mining.
Once you learn more about BTC you will find more ways than I can think of at the moment to earn BTC whether via methods similar to the ones discussed above, to bitcoin integration services for local businesses, white glove miner setup and hosting offerings (i.e you do all the work and become a persons cloud mining provider) and as I said, more than I can name. Check out ebay, the marketplace forum here and other locations and see how others in the community are making their BTC fortunes, follow their lead or create a money making strategy based on theirs.
If your still very new to BTC and are interested in understanding mining, I'd be more than happy to send you a few usb miners for free so you can get a better understanding of the process. I only ask that you pay the 5$(if in the US) for the priority shipping box, so if you want a few block erupters and maybe a antminer shoot me an address to send to and send 5 dollars to my btc addy or i'll give you a paypal address to cover shipping.
Anyway, I wish you luck and if you ever become one of the bitcoin billionaire whales, I am always accept donations for my daughters MIT fund
Good luck and Take Care,
Detro
