Then you must know how Bitcoin works?
What does proof of work and public key cryptography have to do with Bitcoin? Are Bitcoins encrypted and signed or are they only encrypted or only signed, and why?

When I send Bitcoins to you, are they stored on your computer or are they stored somewhere else, and if yes, where?

You don't have to answer these, but you said it yourself you've been around for about 1 year and you sounded very self-confident, so I got curious of your knowledge and if you know Bitcoin the cryptocurrency.
