That... and nobody will be sending micro payments of 1 penny (that is literally what 0.00000001 bitcoins works out to if it was indeed worth 21 trillion USD or the equivalent)...

Especially not in the year 2025 by the time we actually take this to a global scale.

Honestly, tell me. For what reason would you need to transfer a penny across the ocean?

Not to mention fees are not required. If you really want to send a penny, you can probably afford to wait an hour for a confirmation.
