Hello,
if you are looking for a daily income and don't want to trade yourself, finding a business is a very difficult task. There are - among others - two things you could do:
1. MiningThere are many mining pools out there. My advice on all them: Don't. Mining - in my view - is not an attractive investment anymore. The price per GH/s is simply too high with most of the sites out there. What's worse: You will never know how difficulty changes. With so many orders on new mining gear that could hit the consumer, the overall hashing power might increase big time making mining even more difficult.
Trading There are websites out there that do the trading for you and will pay out the gains on a daily level. There has been much talking about one particular website lately that I personally have tried as well.
bitcoin-trader.biz (there is my ref link in the link)
They do mining and trading. Forget about the mining (because of the reasons already stated). Their trading option is worth a look, though, if you are confident that they are legit. And this is the question with many, many, many, many Bitoin related web offers. In case of BT we don't know.
What we do know:
1. Your initial investment that they use to trade, will be blocked for 120 days. During those four months you will get a daily (Monday to Friday) payout that you can cash out or reinvest. After 120 days you will get your principal back.
2. They exist since November 2013 and so far have been paying all their investors. Unfortunately, this is no proof that they are legit. There is chance that they are paying their old investors with the money paid by new ones. We simply don't know.
3. If they are legit, then their offer is fantastic as they pay out around 0,8 percent at the moment. They do this with arbitrage trading, a method where you exploit different prices of Bitcoin on different market places to your advantage.
BT sells shares at 20 USD per piece so you could start with little money. Personally, I invested significantly more. Still, it's part of my previous gains I achieved with Bitcoin so it does not hurt as much if BT runs away. But I don't think that this will happen.
I hope that helped - good luck with your investment
