Internet reports that U.S. President-elect Donald Trump promised during the campaign to build a strategic reserve of Bitcoin held by the U.S. government. However, quantum computing technology continues to make breakthroughs, making the fate of Bitcoin and other cryptocurrencies seem confusing. The US "Wall Street Journal" reported on the 23rd that some people are worried that the continued development of quantum computing may allow hackers to crack the encryption technology that ensures the security of Bitcoin, thereby stealing Bitcoin. The report quoted researchers as saying that it will take ten years or more for quantum computing devices that can crack Bitcoin encryption technology to be born, but the development of quantum computing technology poses long-term risks to Bitcoin unless Bitcoin developers upgrade encryption technology. However, cryptocurrency professionals believe that upgrading Bitcoin encryption technology will take years. Given the decentralized nature of Bitcoin, upgrading encryption technology requires a broad consensus among defenders of the "currency circle" around the world. The Wall Street Journal quoted analysts as saying that if hackers use quantum technology to attack Bitcoin, it will affect traditional financial markets. (Xinhua Agency)
