There are already some exchanges doing the interest and allowing people to get loans to invest ,called margin trade ,and there are lending program running at some exchanges already as poloniex,bitcoin wont have a fiat bank connected to bitcoin world atleast not now.
yeah but this is different, the thing that exchange those is to encourage the usage of their exchange and you put your money at risk, with this idea of banking give you interest, you don't really invest
you just lock your money like in any normal bank for a year, and they give you 10%, your funds should be fully covered by the government, otherwise it may look like a ponzi...
I doubt bit holders of bitcoin would be interested into those,their name will be connected to the fortune,the most bitcoin holders love the fact they are anonymous and rich soo why to change,besides those bitcoin purpose is take control of our money from them soo why to let the money for 1 year or more at some bank backed by government ? To they control you ,they say you cant retire or you will loose those income and a fee willl be taken off?We can get those income investing time,and being doing some lends ,exchanges montly soo why to let others control once again our bitcoin, no way.
