IMO, Bitcoin is more efficient as a mode of exchange cos it doesn't need someone to mind it (as with your bank accounts). So If I want to transfer $100,000 to Germany because I'm relocating, I don't have to deal with any of the regulatory bullshit that is going to take 2 weeks and $300 just to get my own money. I simply use bitcoin and all of the taxes and fees are gone.
Is it good for me? OFC! I hope Bitcoin will be our future.
