Of course bitcoin is a scam. It’s a “currency” you can’t spend anywhere. It’s only purpose is a pump and dump scheme for early adopters.

if I take a hoop/window and place it quickly over an object

Then the velocity of the object relative to the “exit” of the hoop would be the same as the velocity of the object relative to the “entrance” of the hoop, which is option B.

In your analogy, option A would mean the object has a relative velocity of entering the hoop but suddenly no relative velocity exiting it, so the object magically starts following the hoop.
