The centrally placed ‘B’ in this round is surrounded by several currency symbols, suggesting that Bitcoin is superior to the dollar, euro, and yen, as well as silver and gold. The round prominently features a complex mathematical equation; a first for physical crypto-currencies. The equation is taken from the Bitcoin white paper by Satoshi Nakamoto which laid the foundations for Bitcoin. A ‘51% attack’ is a legitimate concern for Bitcoin, as it is technically possible for someone who controls 51% or more of the total mining power to essentially ‘hijack’ the blockchain and manipulate it.
