Is there any upcoming project that would act like a bitcoin savings account?
There are so many of this on Facebook and they are called hyip or double or lending platform just like MMM founded by Mavrodi but be careful with this kind of sites or programs,majority of them are scam sites,I've not yet seen a trustworthy investment sites that uses Bitcoin.
Hyip is not a bitcoin savings account type business. Hahaha. It is the vice versa. There are so many ICO that has a feature like this just like chronobank and polybius. Try investing on an ICO that has a banking system platform and avoid hyips.
