I think Bitcoins will be well tinted at end. Since BTC community will kneel infront of banks and governments as long they will help with adoption. That si why i dont see Bitcoin will be main world currency on long run.
If bitcoin 'needs' banks and governments for adoption there is something wrong in my opinion.
Just like we don't need banks and government to love certain music, it should be your own choice.
They can and already do have a major influence on bitcoin, unfortunately.
