I don’t think anything is ever going to happen. I agree that bitcoin has become quite a big name in recent days but it is not that big that it can destroy a complete economy. There are so many other factors that might contribute to the destruction.
There's always the possibility so it's not completely a fiction that bitcoin's going to destroy the economy, remember that it's an unusual investment tool so it's likely that its not going to do so but I am on your side, it's just that I want people to see that there's endless possibilities, be it worse or better.
