It seems not to fall from bad news anymore:
People are used to bad news about bitcoin vs govt and banks, in fact bitcoin fans are anti govt and anti banks and it is good PR that govt and banks try to shut down it.
It is just matter, at some point govt and banks it will really shut down all the exchangers, not just press, at that time if people can't buy or sell bitcoins, I wonder, perhaps price keeps the same, just with small volume.
