How miners use solar energy for cryptocurrency mining, saving 75%



The energy of the Sun, if used in the mining of cryptocurrency , reduces the cost of electricity by 75% – said the owner of the mining company in Sweden, Christian Ander. According to him, the solar panels installed on the roof of his house have become a real boon in terms of managing the cost of Bitcoin mining, when its cost is almost five times less than the historical maximum for this cryptocurrency.

Ander says that he has a double benefit: the energy of the Sun for the needs of his household, and not just for mining. He also explained why such savings were achieved: when buying kW of energy from the grid, the consumer inevitably pays various taxes and fees, which the supplier includes. If you "mine" solar energy, then this article is no waste.

In Sweden, an additional impetus to the use of solar panels appeared following the decision of Stockholm to abolish the need to pay the appropriate building license from August 1, 2018 – this practice had previously caused dissatisfaction among local residents, who were first recommended by the authorities to install such equipment, and then began to charge, including retrospectively.

In the United States, the largest cryptocurrency market in the world, the prospects for using solar energy in mining are also great. Currently, solar energy is an industry that "weighs" $ 28 billion and gives about 1% of all electricity in the country.

In both Sweden and the United States, over the past four years, the volume of capacity that is engaged in the extraction of such energy has increased two and a half times. It draws attention that China is one of the main producers of solar panels in the world: 80% of such equipment, which is then installed in the United States, is imported.

According to a CoinShares study , the share of renewable energy sources, including the Sun, accounts for about 80% of all electricity consumed in the production of cryptocurrencies.

Meanwhile, a study by PricewaterhouseCoopers, published on March 14, showed that corporation analysts believe that the issue is not so simple. In their opinion, the use of alternative energy sources for mining Bitcoin still does not solve the issue of excessive consumption of electricity, which can be solved by, for example, changing the protocol for achieving a concessus on the network.

US SEC Commission: Some Stablecoins May Be Recognized to Securities



According to Valery Schepanik, senior consultant for digital assets of the United States Securities and Exchange Commission (SEC), the norms of securities legislation may apply to certain types of glasscoins . Reported Decrypt .

According to Shchepanik’s classification, one stablecoin can be tied to real assets like gold or real estate, the other to fiat currency, and the third to use various “financial mechanisms that support price stability.” It is the third category, in its opinion, that can become the object of close attention of the regulator.

“I came across steyblokinoy, the value of which controls a certain pricing mechanism associated with the emission, creation or redemption of another type of digital assets tied to them. Or, it is supported by control over the ratio of supply and demand in order to keep prices in a certain range , ”said the SEC representative.

According to her, if the central side controls the steakblock's price volatility, or if the buyer is promised a guaranteed income or a controlled price, such an asset can be recognized as a security.

She noted that the agency applies equally to all cryptocurrency projects. Shchepanik also emphasized that companies should contact the agency for consultation before the release of the token , and not after:

“We would prefer that people turn to us for permission or advice before they do something, rather than do something first, and then come to ask for forgiveness.”

Japan will consolidate the rules for cryptocurrency in the category of "cryptographic assets"



The Cabinet of Ministers of Japan proposed amendments to the laws “On Financial Instruments and Exchanges” and “On Financial Settlements”. Thus, it is planned to consolidate a number of norms regulating the market for digital assets.

The Law “On Financial Instruments and Exchanges” is aimed at ensuring the transparency of markets and the safety of investors. It contains clear requirements for operations with derivatives and securities.

Several points may be added to Japanese law.

So, it is proposed to make cryptocurrency in a separate category – “cryptographic assets”. This is consistent with the definition adopted by the G-20 countries. Companies that deal with their exchange will receive the status of "agents for the exchange of cryptographic assets."

Cryptocurrency exchanges may be required to keep clients' funds in cold wallets. If for these purposes it is necessary to use the infrastructure that is connected to the Internet, then the assets should be provided with their own funds of the exchange.

Margin trading of digital assets is proposed to regulate by analogy with the markets of foreign currencies.

"In addition, cryptocurrency companies can prohibit the use of promotional materials that encourage speculation and indulge in dishonest practices (price manipulation, insider trading, etc.)."
