Investment in digital currency, aka cryptocurrency, is increasingly prevalent throughout the world, including in Indonesia. This is because the cryptocurrency profit potential is high, although at the same time the risks faced by investors are also high. The high profit potential of cryptocurrency investment is supported by price increases that are beyond common sense. Quoting the coinmarketcap.com site, the price of one of the cryptocurrency, namely bitcoin as of December 31, 2016 was at the level of US $ 960 per 1 BTC. A year later or exactly 31 December 2017, the price of 1 BTC is equivalent to US $ 12,952. That is, the price of bitcoin grew by 1,250% in a year.
