Recently, the "currency circle" has suffered another wave of earthquakes. Bitcoin has fallen one after another, from above the 70,000 US dollar at the end of July to about 58,000 US dollar on August 16. Especially on August 5, Bitcoin once fell below the 50,000 US dollar, a new low in nearly a year, with a drop of 15% in the day. More than 270,000 people liquidated their positions, and the total amount of liquidation exceeded 1 billion US dollars. Our country has always maintained a strict supervision of virtual currencies. Previously, the People's Bank of China and other departments have issued notices on preventing and handling the risk of speculation in virtual currency transactions on many occasions, making it clear that virtual currencies do not have the same legal status as legal currencies, and virtual currency-related business activities are illegal financial activities. Since the beginning of this year, regulatory authorities in many places have warned of risks, asking the general public to be vigilant, consciously stay away from illegal financial activities such as "virtual currency" trading speculation and illegal fund-raising, and beware of personal property losses. If you participate in it, you should withdraw as soon as possible.
