i believe they will try to take it down and one way or another they will probably succeed.  It is to our interest to stick to our grounds and grow, support and stabilize the movement.  I would never invest all my savings or even a substantial amount of them.  But what i suggest is that everyone converts an amount (which if lost is not detremental ) to bitcoin with the intention of never converting it back to $$.  As i said they will try to take down bitcoin if it tries to completely dominate.  If everyone followed this it will grow slow and strong with heavy roots.  Lets not be greedy people!
