Donald Trump's policies on cryptocurrency profits were mixed and sometimes contradictory. Initially, Trump was skeptical of cryptocurrencies, suggesting that Bitcoin and other digital currencies could pose a threat to the US dollar. In a famous tweet from 2019, he stated that he preferred traditional fiat currencies and that digital currencies could be "fraudulent".
However, in later periods, there were indications of increased interest in the development and issuance of government-backed digital currencies, such as the digital dollar. On the public policy front, the Trump administration focused on tightening regulations related to cryptocurrencies, such as prosecuting illegal activities like money laundering and terrorist financing using these currencies.
Furthermore, during his presidency, there were indications of support for certain technological innovations that could contribute to the improvement of digital currencies, but within a strict regulatory framework. Thus, Trump's overall stance tended to lean towards caution and an emphasis on regulation rather than full adoption of cryptocurrencies.
