During his tenure, Trump's attitude towards cryptocurrencies has always been quite complex. He has criticized Bitcoin and Facebook's Libra (now renamed Diem) project, believing that they could threaten the global status of the U.S. dollar. However, as cryptocurrencies become more popular and mature, Trump and his team have also begun to recognize the potential of this emerging asset class. In the re-election campaign, Trump may propose a clearer cryptocurrency policy to attract the growing group of digital currency investors.

The breakthrough of Bitcoin's price at $90,000 marks another important milestone in the cryptocurrency market. This achievement not only represents investors' recognition of the value of cryptocurrencies but also indicates that cryptocurrencies are becoming increasingly important in the global financial system. As more and more institutional investors and companies begin to accept Bitcoin as a means of payment and storage, the process of cryptocurrency mainstreaming is accelerating.
