According to Crypto Watch, Japan's GMO Internet Group held a briefing session for the first quarter of 2019. In the published final statement, the company said that the company's sales in the first quarter of 2019 was 46.8 billion yen, an increase of 7.2% over the same period of the previous year. On the other hand, operating profit was 5 billion yen, a decrease of 5.1% over the same period of the previous year. Regular profit decreased by 0.9% year-on-year, and final profit decreased by 3.0% year-on-year. In the increase and decrease of operating profit of each department, the financial and advertising media business made up for the decline in profits of infrastructure and virtual currency business. In the last quarter (the fourth quarter of 2018), there was a huge amount of virtual currency business of more than 35 billion yen. This quarter's sales were 1.29 billion yen, an increase of 103.7% over the same period of the previous year. The operating loss was 220 million yen. The deficit was reduced by 500 million yen in the same period of the previous year. The main reason is that although the turnover of virtual currency trading business has decreased with the decrease of trading volume, the reconstruction of virtual currency mining business has made progress.
