I like the idea but I am quite hesitant to put anything on the line to try it until they have been around a while. I made the mistake once of being the guinea pig and will not do that again.
The Bitcoin stock market is an annoying thing that said they say risk brings reward in this case we have banks not anonymous ones that support the idea and can back it up.
That said it could backfire so it could well be worth just observing for now.
