Description
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.
