The U.S. dollar is backed by the world's most powerful military pumped by $7xx billion dollars annually. So yes, it IS backed by something. Something very large and unfathomably destructive.
Bitcoin is not a currency. A 'virtual currency,' perhaps...but not a currency. It's simply a medium of exchange. Just like credit cards, money orders, paypal, and the likes. IT IS NOT A CURRENCY, no matter what a neckbeard or tinfoil hatter will tell you.
Yes, I know the hardcoin bitcoiners will preach to the choir about their grandeur plot to overthrow the government and have their hipster technology take over as the world's accepted money medium...but that's why the sane general public is laughing and pointing from the outside at their detachment from reality.
Now could it thrive and continue to grow as a medium of exchange? Perhaps. My money isn't betting on that horse, though. Its worth will forever be tied to the dollar, and there will be a better technology released by the government that is an OFFICIAL "currency" that will render bitcoin and all other alts worthless. Yes, I know this saddens everyone. But that's how the world works...the government with the nukes will control the money flow by any means necessary.
