In today's digital age, Bitcoin as a virtual currency is gradually coming into people's view, while the status of the US dollar as a world currency has become stronger and stronger. Former US President Trump once publicly stated that Bitcoin is like a scam, while the US dollar is the world currency. This view has triggered people's thinking about the nature and future development of currency. This article will discuss Bitcoin and the US dollar, and explore the struggle and influence of the two in the financial field.

Bitcoin, as a cryptocurrency, was born in 2009 and was created by Satoshi Nakamoto. Its characteristics such as decentralization, anonymity and limited issuance have attracted much attention. In contrast, the US dollar, as the world's most important reserve currency, is widely used in international trade and financial markets. Trump's questioning of Bitcoin has triggered people's thinking about the trust and long-term stability of virtual currencies.

Bitcoin supporters believe that its decentralized nature makes it immune to government intervention and can exist as a safe-haven asset. For example, during the 2020 COVID-19 pandemic, global stock markets plummeted, but Bitcoin performed well and attracted more investors' attention. In contrast, although the US dollar is stable, it is subject to the influence of national policies and economic fluctuations, and there is a risk of inflation and depreciation. In this case, Bitcoin is regarded by some as the digital gold of the future, which has certain hedging properties.

However, Trump's negative comments on Bitcoin are not without reason. The virtual currency market is highly volatile and has a high risk of speculation. At the end of 2017, the price of Bitcoin once soared to $20,000, but then plummeted rapidly, causing many investors to suffer huge losses. In contrast, as a legal currency, the US dollar has strong stability and liquidity, and is widely used in various fields around the world, providing convenience for international trade and financial transactions.

In international trade, the position of the US dollar is unshakable. Most international trade is denominated in US dollars, and the issuance and credibility of the US dollar have been recognized globally. At the same time, the legality and regulatory issues of Bitcoin have also become obstacles to its development. Many countries are cautious about Bitcoin, fearing that it will be used for illegal activities, leading to doubts about its legality. Therefore, although Bitcoin has performed well in some areas, it still has a long way to go to surpass the status of the US dollar in the international monetary system.

In general, Bitcoin and the US dollar have their own advantages and disadvantages, and each has a unique role in different fields. As an emerging virtual currency, Bitcoin has innovation and potential, but its risks cannot be ignored; and as the world currency, the stability and liquidity of the US dollar make it play an important role in international trade. Trump's negative comments on Bitcoin have triggered in-depth thinking about virtual currencies, and also reminded people to be cautious in investment and financial management and treat various assets rationally.

In the future, Bitcoin and the US dollar may have more games and cooperation in the financial field. With the continuous development of science and technology and the changes in the global economic landscape, people's demand for the form and function of currency is also evolving. Perhaps, in the near future, we will see Bitcoin and the US dollar jointly build a more diversified and stable monetary system, injecting new vitality into the development of the global economy. Let us wait and see and witness the future of currency.

Former US President Donald Trump has always despised Bitcoin. In a recent media interview, he directly criticized Bitcoin as a scam, depriving the importance of the US dollar, which is the real world reserve currency.

Coin Circle previously reported that the Central American country of El Salvador is seeking legislation to become the first country in the world to use Bitcoin as legal tender. Currently, the US dollar is the only legal tender in El Salvador, which means that if the proposal is officially passed, the legal status of Bitcoin in the local area will be on par with the US dollar.

In response, Trump reiterated his negative stance on Bitcoin in an interview with FOX Business yesterday (7). He said: "Bitcoin, it looks like a scam, I'm surprised - you know, it was only worth $6,000 or even less when we were in office. I don't like it because it's another currency that competes with the US dollar." Trump also said that the world currency should be the US dollar and called on the authorities to regulate Bitcoin. He said: "I think they should regulate them very, very strictly, and the currency should be the US dollar." In fact, as early as July 2019, Trump said during his tenure that he was not a supporter of Bitcoin and cryptocurrencies. He also pointed out that cryptocurrencies are not currencies, their value is based on thin air, and they are extremely unstable. Moreover, unregulated crypto assets will promote illegal activities, including illegal transactions. Last June, former White House National Security Advisor John Bolton broke the news in his new book that Trump had ordered then-Treasury Secretary Steven Mnuchin in 2018 to focus on suppressing Bitcoin instead of focusing on China trade negotiations. Finally, the U.S. Treasury Department issued controversial crypto wallet regulations before the Trump administration left office. Now, the Biden administration has further expanded the Trump-era policy, requiring financial institutions to report on cryptocurrency users' transfers of more than $600, and has begun to develop a new cryptocurrency regulatory framework to examine related regulatory loopholes.
