according to foreign media reports, with the growing popularity of bitcoin, central bank governors around the world have also expressed their views on this digital currency

Federal Reserve Bank of the United States

in December last year, at the monetary policy meeting of the Federal Reserve Bank of the United States, Janet Yellen, chairman of the Federal Reserve Board, was asked what she thought of bitcoin

According to Yellen, this kind of digital currency is a "highly speculative asset" and "cannot be legal tender". She added that it "plays a negligible role in the payment system" and that it "is not a stable store of value."

"the Federal Reserve Bank will not make any policy on bitcoin. Instead, we will only ensure that the banking institutions we supervise pay close attention to digital currency and properly manage their interaction with traders in the market. Moreover, we will monitor whether these banking institutions have fulfilled their responsibilities to combat money laundering and ensure the safety of banks. " Yellen said

at the end of November last year, Jerome Powell, who will replace Yellen as chairman of the Federal Reserve in February this year, also expressed his views on cryptocurrency. Cryptocurrencies "don't matter now" because "they're not big enough," he said

According to Powell, the financial risk brought by digital currency to the financial market is minimal“ They're not big enough, they don't matter now. " He said

European Central Bank

in October last year, Mario Draghi, President of the European Central Bank, said that cryptocurrency was not "mature" enough for the central bank to regulate management

"for anything new, people are always full of expectations, but also feel very uncertain. Now, as far as bitcoin and other cryptocurrencies are concerned, we don't think they are mature enough for us to consider standardized management. " He said

Draghi pointed out that tools like bitcoin have both advantages and disadvantages, and we need to weigh them carefully

"a lesson of the great financial crisis is financial innovation. As far as bitcoin is concerned, it is a financial and technological innovation. We should pay close attention to its potential risks while paying attention to it. " He said

Bank of Canada

in December last year, Stephen poloz, President of the Bank of Canada, also spent some time discussing cryptocurrency. He claims that buying digital currency is a gamble, not an investment

"perhaps no one can say clearly what their real value is. One can at most say that buying digital currency is buying risk. This makes it closer to gambling than investment. " "For people who want to buy cryptocurrency, what I want to say is that you should read the collateral to make sure you know what you're investing in," boloz said

According to boloz, the demand for digital currency will increase in the future. He added that the Central Bank of Canada was studying whether to issue its own digital currency

"bank staff are studying the conditions under which the central bank is more suitable to issue its own digital currency for retail transactions." He said

Reserve Bank of Australia

in December last year, Reserve Bank of Australia President Philip Lowe talked about bitcoin in a speech. He pointed out that this kind of digital currency will not be used in daily payment activities, and it can not be accepted so soon

According to Lowe, the reason is that the price of bitcoin is extremely unstable, the number of payments that can be processed at the same time is limited, the transaction and electricity costs are too high, and the management is too difficult

moreover, when bitcoin is only used as a payment tool, it "is more likely to attract those who want to trade in black or illegal economic activities."

Bank of Japan

at the end of 2017, Haruhiko Kuroda, President of Bank of Japan, said the price fluctuation of bitcoin was "extremely abnormal"

when asked if there will be a bubble in bitcoin, he replied, "I may not be qualified to evaluate it, but if you look at its trend, you will see that its price fluctuation is very abnormal. If you want to ask whether bitcoin has the same function as money, that is, as a payment or settlement tool, then my answer is No
