When you ask a question you should base it in reality, not in your fictions. Your question is nonsensical. Both parts of it. In the second part you are mentioning bitcoin. But... where's bitcoin?
The same can be said for your questions as well. Your questions are nonsensical.
"Where is Bitcoin?" Bitcoin is a digital currency, like everything else digital, it doesn't exist in the physical world.
(There are physical representations of it, for example collectors' items.) It is a type of information stored on digital media. Now, tell me, can you comprehend the concept of information that has value (to someone)? If you cannot, stop wasting our time and yours. If you can, stop using faulty arguments like "bitcoin doesn't exist". To the same extent, no information exists either.
Paying for symbols to be attached to your name is a human behavior.
Everything we do is human behavior. Your statement has no relevance.
One can as well pay after you sent a number to their email address.
And I'm sure many people are doing just that. You obviously have never worked remotely.
