This is a unique idea that I haven't heard before. Any idea what these 'banks' might use the Bitcoin for? With the upcoming Lightning Network additions, this might make an interesting use case where "decentralized banks" are able to help aid the network with payment channels and its members gain interest. By the way, Bitcoin mixers are sorta like this in a way. If you have enough Bitcoin, some mixers look for investments and promise to return interest from it. This is another potential use case for "decentralized banks".
