According to Tencent Technology, the mining machine manufacturer Bittland has secretly submitted a listing application to the US Securities and Exchange Commission a week ago. The sponsor is Deutsche Bank. According to informed sources, from the initial target Hong Kong stocks to the current US stocks, Bitco's IPO process has been dominated by Wu Jihan and CFO Liu Luyao, and the Jank Group is less involved. In order to increase the chances of success in this trip to the US, Bittland even hired Zheng Hua, the former representative of Nasdaq's former China region, as a consultant to the company. The strong return of Wu Jihan means that if it receives shareholder support, Bitian will focus on the most advantageous blockchain industry, regrouping in the mining machine and mining pool business, and launching an impact on US stocks.
