I think bitcoin can go both ways -
1. It'll hit skyhigh - tens of thousands to hundreds of thousand
2. It'll die. Just die, completely.
I'm hoping for the first option, but IMO it's pretty unpredictable.
easier to predict that it cannot die. it's already accepted in most countries, it's already being used by thousands of businesses (http://coinmap.org/), and ten's of thousands of businesses use Bitpay to accept bitcoin related transactions.
Impossible to kill off now.
It's too late to shut the stable door after the horse has bolted
EDIT. these are few well known places that accept BTC: Amazon, Richard Branson-buy a trip to space, University of Nicosia, bitcoin ATM's, etc, etc...
I agree, Bitcoin cannot die completly no matter what happens, there are people who will use it regardless of value or laws...
