The Bank's FUD against Bitcoin is actually why Bitcoin is such a good thing.

1 - "No one is backing it". Exactly! If "one" is backing it, "one" is controlling it. That "one" is not the person whos' money it is. For the USD, the "one" who backs it is now over 20 Trillion USDollars in debt. The fact is that Bitcoin is backed by MATH. Even aliens can't argue with math. Math can never go into debt.

2 - "Users are not protected". Actually, since each user controls their own Bitcoin, they are protected from bank runs, inflation, banks cutting the Users off from their money on a whim. Bitcoin protects Users from banks!

3 - "It is not widely accepted" After only 9 years of existence, Bitcoin is accepted worldwide. No fiat currency, not even the almighty USD is accepted worldwide. When Bitcoin is as old as USD, it will be Universally accepted. Since it is backed by Math, even aliens will accept it.

4 - "It is too volitile" Fiat currencies are not volatile - they constantly decrease in value due to inflation. Bitcoin is volatile because it is the world's first Natural Market and the market is very young. As adoption increases, volitility will decrease and its value will increase because there is only a limited supply, unlike fiat currency, where the "ones" who back it constantly create more and more of it.
