You will get paid for your deposit, you're not going to get scammed and you won't have to do anything (passive income) but you will not double your money or something like that. I recommend that you put in a good quantity (1 million satoshi let's say) and leave it there some time.

I came across this bitcoin platform last year. Originally I had problem trusting it - it is Chinese btw, but eventually they did enough to convince me that it is a legitimate. The company controls lots of hash power in western china, which is where their interest payment is from. They originally pay 15% per year but now redued to 8% - sucks. IMO, this is a legitimate service that worth some of your bitcoins, not all for sure, but some.

I came across the website on bitcointalk where there is a long thread about it. I made a deposit and so far so good. There is no sign of scam going on. There are sufficient proof in photos and video. But that said, you shouldn't invest more than you can afford to lose.
