Guys here, maybe you missed or don't care to read Don Pedro Dinero's post. As he said and I agree too, there is onr known wallet which pays you for holding money and that's freebitco.
It's a little different, you receive percent weekly but if you withdraw money everytime, if I amn't wrong you can't get % on whole deposit. I mean that you have to keep bitcoin weekly in order to get some percent from them. Better to read rules and you'll understand everything, it will take some time from me to explain everything.
Just to clarify a little detail, below is the quoted explanation from their site and I've bolded them for tl;dr case
You will get daily interest from freebitco, I can say that for sure as they have a table of detailed income from this interest, which include the date and amount received.
It's quite an old thread, so I am not sure if the OP even still visiting this thread or not, but a little advise that I should include (or rather a disclaimer that I didn't hold any responsibility if something wrong happen) to anyone that's interested on this, you have to use your own common sense when using this feature. I've been using freebitco for a long time and never had any issue with them, I am not against them at all, but if you want to deposited your money into their site for this feature, keep in mind that you didn't hold your private key and you can't control your balance in case something wrong happened one day. Never invest more than you can afford to lose.
Receive compounded daily interest on any balance that you hold in your FreeBitco.in account, without doing anything.
All you need to do is mantain a balance of at least 30,000 satoshi (0.0003 BTC) in your FreeBitco.in account and we shall pay you compounded interest on your full balance everyday. There is no lock-in period to earn interest (you start earning interest right from the first day!) and your balance can be withdrawn any time you wish. Treat your FreeBitco.in account like an instant-access savings account to hold your excess bitcoins and earn passive interest on your account balance everyday.
