Is there any upcoming project that would act like a bitcoin savings account?
If you want to invest your bitcoins, don't. There are simply so many scams out there, the legit sites like Genesis Mining don't make you any sort of profit at all because they need to make profit, and they do so via charging fees. For them to make profit in a bitcoin environment where the difficulty is so high they must be able to charge you a lot of fees, and terminate your contract when your earnings cannot sustain the fees they charge.
P2P lending is bad, Bitlendingclub and a few others basically went under a few months ago. These accounts actually can get bought by people, meaning that for the risk you're taking on, the returns are miniscule.
Poloniex lending used to be good, but now the company is having liquidity issues. Magnr offers interest, but it's negligible. Your year's worth interest is going to be eaten up by miner fees.
The main reason of holding bitcoin is to have control over your own wealth anyways. Bitcoin is disinflationary, meaning that in the long term you are guaranteed to make a profit. Why would you have BTC, and still have to trust someone with it?
