How safe is bitcoin guarantee

1. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system

unlike all currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

extended data:

influencing factors:

1. Ministry of Finance (MOF): Japan's Ministry of finance is the only department to formulate fiscal and monetary policies. Japan's Ministry of finance has more influence on the currency than the United States, Britain or Germany. Officials of the Japanese Ministry of Finance often make some comments on the economic situation, which will generally have an impact on the yen. For example, when the yen is not in line with the fundamentals of appreciation or depreciation, officials of the Ministry of finance will make oral intervention

Bank of Japan (BoJ): Bank of Japan. In 1998, the Japanese government passed a new law that allowed the central bank to formulate monetary policy independently without the influence of the government, while the yen exchange rate was still in the charge of the Ministry of finance

3. Interest rates. Overnight lending rate is the main short-term interbank rate, determined by BoJ. BoJ also uses this interest rate to express the change of monetary policy, which is one of the main factors affecting the exchange rate of yen

Japanese government bonds (JGBs): Japanese government bonds. In order to enhance the liquidity of the monetary system, BoJ will buy 10-year or 20-year JGBs every month

The yield of 10-year JGB is regarded as the benchmark of long-term interest rate. For example, the basis of 10-year JGB and 10-year US Treasury bills is regarded as one of the factors driving the trend of USD / JPY interest rate. A fall in JGB prices (i.e., a rise in yields) usually benefits the yen

Economic and financial policy agency: Department of economic and financial policy. It officially replaced the original economic planning agency (EPA) on January 6, 2001. Responsibilities include elaborating economic plans and coordinating economic policies, including employment, international trade and foreign exchange rates

Ministry of international trade and instry (MITI): the Ministry of international trade and instry is responsible for guiding Japan's instrial development and maintaining the international competitiveness of Japanese enterprises. However, its importance has been greatly weakened compared with that in the 1980s and early 1990s, when the volume of Japan US trade would influence the foreign exchange market

Economic data: economic data. More important economic data include: GDP, Tankan survey, international trade, unemployment rate, instrial proction and money supply (M2 + CDs)

Nikkei-225: Nikkei 255 index. Japan's major stock market index. When Japan's exchange rate is reasonably lower, the share price of export-oriented enterprises will rise, and the Nikkei index will also rise. Sometimes, this is not the case. When the stock market is strong, it will attract foreign investors to invest a lot in the Japanese stock market, and the yen exchange rate will be pushed up

Cross rate effect: the influence of cross exchange rate. For example, the rise of EUR / JPY will also lead to the rise of USD / JPY. The reason may not be the rise of the US dollar exchange rate, but the different economic expectations for Japan and Europe
