Donald Trump earned more than $1.4bn from his family's cryptocurrency ventures last year - all while pursuing policies to benefit the industry.
A new financial disclosure reveals that the US president received $635m (£479m) of this income from "memecoins" bearing his name.
He had controversially launched the $TRUMP coin days before his inauguration last year, but the digital asset's value has plunged by more than 97% since.
In an attempt to encourage purchases, Mr Trump has held special dinners for top investors, with well-known crypto entrepreneurs among those in attendance.
The filings from 2025 go on to reveal that he received more than $500m (£377m) from World Liberty Financial, a crypto company he co-founded with his sons.
Some Democrats have previously warned that the president's activities in this industry are a conflict of interest that could endanger national security.
In a letter last year, Senator Elizabeth Warren wrote: "Anyone, including the leaders of hostile nations, can covertly buy these coins, raising the spectre of uninhibited and untraceable foreign influence over the President of the United States."
Mr Trump's financial disclosure, covering the first year of his second term, runs to 927 pages. Barack Obama's final form was nine pages long, and Joe Biden's was 11.
A White House representative said in a statement: "Neither the president nor his family has ever engaged - or will engage - in conflicts of interest."
Throughout his presidential campaign and since entering office, Mr Trump has vowed to make America "the crypto capital of the world".
He has supported legislation including the GENIUS Act, which creates regulations for stablecoins - a cryptocurrency that's designed to mimic the US dollar.

Last year, he pardoned the founder of a major cryptocurrency exchange that had failed to maintain an effective anti-money laundering programme.
The president has also pledged to create a strategic reserve that would hold Bitcoin on behalf of American taxpayers, but this policy is yet to materialise.
Mr Trump's pro-crypto stance had helped Bitcoin accelerate to an all-time high of $126,272 (£93,500) last October. However, the world's biggest cryptocurrency's value has crashed by more than 50% since then.
Unlike past presidents, Mr Trump did not divest his assets or place them in a blind trust before taking office.
Douglas Brinkley, a history professor at Brinkley University, told Sky's US partner NBC News: "What strikes me as remarkable is how many pies Trump has his fingers in.
"There is no precedent to compare it with. No president in the 20th or 21st century has had something that's vaguely comparable."
