The surge in interest around blockchain technology has propelled blockchain-related stocks on the A-share and New Third Board markets into the spotlight. Currently, over 30 A-share companies are categorized as blockchain concept stocks, while in the New Third Board market, firms such as Caima Network (430361), Taiyiyun (430070), Jinqiu (837901), and Huazheng (833166) have also made significant moves into the blockchain space.
In addition, it has been revealed that a dedicated "blockchain army" is actively targeting the New Third Board market. On August 30, 2017, one such company submitted an application for listing to the stock transfer system, which is now under review. This company is one of the top three Bitcoin mining chip manufacturers in China: Hangzhou Jianan Zhizhi Information Technology Co., Ltd. (referred to as "Jianan Zhizhi").
Jianan Zhizhi operates within the upstream segment of the Bitcoin industry chain, producing the core chips used in Bitcoin mining machines. Enthusiasts use these devices to "mine" Bitcoin, which involves solving complex mathematical problems to validate transactions and earn new coins.
Over recent years, the growing popularity of Bitcoin has significantly boosted Jianan Zhizhi's performance. In 2015, the company generated revenue of 55.173 million yuan and a net profit of 2.453 million yuan. By 2016, its revenue had jumped to 316 million yuan, with a net profit of 58.066 million yuan. During the first four months of 2017, the company reported revenue of 255 million yuan and a net profit of 32.693 million yuan.
China currently leads global Bitcoin mining production, accounting for approximately 80% of the total output. As of April 2017, Jianan Zhizhi had sold roughly 160,000 Avalon series mining machines, representing 22% of the global Bitcoin computing market.
Due to the nature of their business, Jianan Zhizhi’s customer base is largely composed of individual users. Out of approximately 400 customers, only two—Guangzhou Jiesai and Tianjin Garment Import and Export—engage in resale activities, while the rest are individual buyers, with over 97% based in China.
Despite the rapid growth, the Bitcoin mining industry faces increasing regulatory scrutiny. In China, the sector is still in its early stages but is at risk of being targeted by regulators. Since 2013, the central bank and other ministries have warned about the risks associated with Bitcoin, emphasizing that it is not a legal currency and lacks official backing.
In August 2017, a regulatory crackdown began on virtual currency trading platforms. ICOINFO, a major domestic platform, suspended all initial coin offering (ICO) activities. Later, on September 4, the central bank and seven other ministries banned ICOs, leading to the shutdown of major exchanges like Bitcoin China, Firecoin.com, and OKCoin.
Following the closure of exchanges, the focus shifted to Bitcoin mining operations. Reports emerged in January 2018 about potential crackdowns, with the central bank holding closed meetings to consider shutting down mining facilities. Subsequently, the Securities Times indicated that domestic Bitcoin mines would not be subject to blanket closures but would instead face targeted regulation.
As regulations tighten, the future of the Bitcoin industry in China remains uncertain. With nearly 99% of the revenue coming from domestic operations, how long this industry can sustain itself under increased oversight is unclear.
Solar Charge Controller
Solar Charge Controllers manage voltage and current from solar panels to batteries, preventing overcharging and optimizing Battery life for reliable energy storage.
Usage:
Solar charge controllers are used in off-grid solar power systems, such as solar street lights, solar water pumps, RVs, boats, and remote cabins. They are also used in grid-tied solar power systems with battery backup to manage the flow of electricity between the solar panels, battery, and grid.
Working principle:
Solar charge controllers work by monitoring the voltage and current from the solar panels and adjusting the charging parameters to maintain the battery at the optimal voltage level. When the battery is fully charged, the charge controller will reduce the charging current to prevent overcharging. Similarly, when the battery is low, the charge controller will increase the charging current to ensure the battery is properly charged.
Purpose:
The main purpose of a solar charge controller is to protect the battery from overcharging and discharging, which can reduce its lifespan and performance. By regulating the flow of electricity from the solar panels to the battery, the charge controller ensures that the battery is charged efficiently and safely. Additionally, solar charge controllers can also provide information on the performance of the solar power system, such as the amount of energy generated and stored in the battery.
