Surely a bank wouldn't move that amount of money with any costs being incurred?
I'm just pointing out its amazing that we can move vasts amounts of money without any paperwork, to anybody in the world for no costs. If that doesn't convince skeptics then nothing will.
You're right, Bitcoin is great for the little guy to move money for
free low cost. Large amounts are moved between branches and banks for free all the time. Think about it a minute, are they going to charge themselves for the move?

My bank even lets me transfer between different accounts at different banks without a fee. My bank may charge a fee for faster service but my credit union offers 3-business-day transfers for free. One day costs $2. So, in theory, I could transfer $126,000,000 for $2 and get it in one day.
You might be able to move $50 between banks for free, but I guarantee that if you ever had 126,000,000 that it would not cost you $2 to transfer. You mad if you think that $2 is a flat fee for any amount.
