this bitcoin savings account pays an initial 2.18% AER until 2016, followed by a variable interest rate tied to the profits generated by leveraged margin trading at BTC.SX. With a 100% reserve guarantee which is independently verifiable via the blockchain, and multi-sig security on all accounts, I would say that the risks associated with this savings account are not significantly higher than keeping coins in your own wallet. It is also quick and easy to set up and requires no maintenance – just like a regular savings account you just make a deposit and leave it there to grow.
