Thank for pointing that out, yes Dimon believes that Blockchain is viable but not Bitcoin. What he is overlooking is that making a law is not that same thing as enforcing it, you can't enforce a law if you can't hold it in your possession.

Also this was his personal opinion, not an official statement.
