Its doooommmsday! haha. Things will be fine. The community in BTC and Alts is enough to keep it from total failure. Belief in the coins can hold it up. Maybe not at these heights. But i like i said yesterday. Im expecting a rinse and repeat cycle every few years. This sudden sharp growth needs to ease off like you've said before. But after the pop and drop i plan to just relax chill and soak up what i can ready for the next movement.
The government can say and do what it wants but ultimately the blockchain is immune to their meddling and if you can trade your coin around the world in places where it remains legal then all is well.

Anyway just keep the faith and watch the action. It will weed out the weak :p
