Even if the governments tried to outlaw it, the exchanges and pools and all operations would just move overseas anyways to a place they could operate.

it's similar to the failed US war on drugs, even with increased enforcement and pouring millions of dollars into anti-drug measures, people will still use them and distribute them.

Bitcoin is being searched so heavily recently too. more people are getting interested in it with the global news coverage and so i do not see it ever being outlawed. the recent developments with the US calling it legitimate help add to my theory that it won't be going away anytime soon.
