Is there any upcoming project that would act like a bitcoin savings account?
I deposit to poloniex then lend my bitcoins using their virtually risk free lending portal, I get good interest on all my bitcoin savings there.
Is it profitable?
Here you see the current rates.
Those are the daily rates (!) so you can easily get 30% per year or more.
The rates jump up often, I've seen it above 1%/day at really speculative times. I would bet its possible to do much better than 30% per year.
Absolutely; but even when the rate drop is structural (a high amount of bitcoins was added about a week ago, so a big whale started to lend) it's a nice result. And because I'm using an intelligent lending bot my results are even better then manual lending gave me before.
