Coincheck earned $490 million before being hacked
Japan-based cryptocurrency exchange Coincheck, infamous for the enormous heist earlier this year, had earned 53.2 billion yen ($490 million) in the period between April 2017 and January, when the hack occurred.
Yet, in February and March, the exchange made a profit of 500 yen. The case illustrates how lucrative can operating a cryptocurrency exchange be. This April a Japanese retail brokerage Monex bought Coincheck for 3.6 billion yen and will be splitting the profit with the previous shareholders for the next 3 years.
