I don't think there is anything such as a bitcoin savings account. What you are asking is for a bitcoin bank which does not exist as of now. And it doesn't make much of a sense to have a bitcoin bank as that would lead to centralization and bitcoin aims to decentralize money.
Taking abut banks, there is a project known as Polybius which aims to be a crypto funded bank. The ICO is still going on. And is about to hit their target. Check ico.polybius.io
You had to bring up a scam ICO into this? do you really think if these kinds of ICOs were legitimate and profitable all of the smart and rich

Is there any upcoming project that would act like a bitcoin savings account?
There is already a project for that if you are comfortable to the interest they are paying and that is freebitco.in. Its a site that have been on the space for quite an amount of time through their faucet platform and other ways such as gambling and lottery platforms. So, you are good to trust them with your money and get your interest even though might be small.
Did you even read at least 3 first posts here mate or just had to repeat like the parrot that you are? freebitcoin, I wonder how would they earn
From bets if it's really a provably fair? I guessed it myself, the house edge is very high.
