Ownership of bitcoin is the ownership of a private key which is simply a 256 bit number that is used in ECDSA for signatures. What if I transform this number into some other form using steganography and embed it in an image, or maybe I just shift it left 100 bits and claim it isn't a valid Bitcoin key and hence I own no Bitcoin. Is ownership of the resulting medium considered to be ownership of Bitcoin? Can I trade it without it being considered cryptocurrency? Can I own it without it being considered to be owning Bitcoin and later convert it back and "acquiring" new bitcoin avoiding capital gains?
