when such gaints can run into a problem, what makes you think they can't be shut down ?
LONG LIVE BTC, 100% UPTIME

Just right now I am experiencing a problem with my facebook account. I cannot make posts and when I checked the reason why, FB said they are making a maintenance check up on my account. Its been more than 3 hours already and still not ok till now. Well, bitcoin may not be as strong as it used to a year ago in value but still kicking, surviving and believed to be returning back in its height soon.
Believe in the power of users, for tens of millions of users still using it, then bitcoin will continue to survive.
there is no perfect system, so is bitcoin. but as long as we believe, bitcoin will continue to be strong
