I´ve read a very interesting posting in the mining community and i want to comment ist herehttp://forum.bitcoin.org/index.php?topic=28438.0
In my opinion JP Morgan & Co. will invest a lot of money in bitcoins otherwise they will loose all her authority and will be needless.
Surely it will taken many years that the bitcoin could replace the dollar, euro, yen, ... but the banks will react long time before they will accept the existence of the bitcoin.
For us private users it is a very good chance to profit in this situation.
Furthermore the big debt in euro, dollar and yen could a lot of people move into the bitcoin to save their money and to kick the bad banks in her a** ;-)
I´m very optimistic that the bitcoin will conquer the world.
