my thinking is as long as the original investment is not divulged which is the primary purpose of the cryptocoin world then how would anyone know at what rate your investment incresed, if you bought bitcoin at .52 and sold it at 1800.00 how could the governemnt state or local or the bank know when you bought it and how much gain you realized so technically it would not be income it would just be conversion, but i think i am under thinking this.
