Yes they have a very good model and we could just copy it. In fact it would be an absolutely great fit for the new BTS superDAC.
Bytemaster talked about how he is working on, on and off ramps for people to be able to pay off their credit cards with bitUSD. Well that's just perfect because most of these people take out loans to pay off their high interest rate credit cards.
That could create HUGE
demand for bitUSD.
I imagine it would work similarly to Bitshares Music. There would be a block chain and a whole bunch of "store fronts" (peertrack). The store fronts would have different models and attract different types of investors. They would be able to pull peoples credit reports and other info to give them an interest rate. The only down side I can see to this is regulation. The store fronts would have to follow regulation and get approval. Some states still don't allow p2p leanding. Luckily lending club has been taking care of this.
