Annual disclosure reveals cryptocurrency has become one of Donald Trump’s biggest wealth generators, intensifying scrutiny over ethics, influence and conflicts of interest.

US President Donald Trump once called cryptocurrency a “scam”. It’s now a major moneymaker for him: his just-released annual financial disclosure shows he made more than $1 billion from cryptocurrency last year.

This news has raised the ire of Trump’s critics. Juliana Stratton, the Illinois lieutenant governor and a Democratic Senate candidate, accused Trump of using his public office “to make billions while American families struggle to afford their basic needs. His infinite greed is disgusting.”

The White House denied Trump or his family has engaged in conflicts of interest. Deputy press secretary Anna Kelly said “all actions by President Trump and his administration are taken in the best interest of the American people”.

But how exactly has Trump earned so much money from cryptocurrency?

How does cryptocurrency work?

A cryptocurrency is simply digital money. It differs from traditional money in two ways.

First, traditional currencies are issued by central banks of each country, while cryptocurrencies are issued according to rules written in computer code.

The computer code behind crypto may be controlled by a company. Or the code may be predefined ahead of time (for example, in a “white paper” that sets up the algorithm behind crypto) and controlled by no one at all.

Second, transactions in traditional money happen via the banking system, while transactions in cryptocurrency happen on blockchains, which are databases that store information on who owns what.

Bitcoin is the oldest and best-known cryptocurrency, with a decentralised structure and no single entity controlling its issuance or making profits off it.

Aside from Bitcoin, there are tens of thousands of privately issued coins, which run on public blockchains such as Ethereum or Solana. But private coins, unlike Bitcoin, are issued by private companies to make money.

Transactions on a blockchain can involve transferring many different versions of private crypto assets – anything that can be written into a piece of code, regardless of whether that digital asset has any value at all.

What are the Trump’s crypto businesses?

Trump and his family are involved in three kinds of digital assets: the $TRUMP memecoin, a governance token called WLFI, and a stablecoin called USD1.

Memecoins are coins with no real business behind them. They derive their value from investor attention – a digital equivalent of buying a kid’s scribble because it’s your kid, not because the scribble has value in the outside world.

Stablecoins, by contrast, are a digital equivalent of a fiat currency like USD. For example, each unit of USD1 is designed to be worth exactly $1. To maintain this value, stablecoins are typically backed by short-term government bonds and cash.

Governance tokens are yet another type of coin, which give holders voting rights over a crypto project, but no ownership over the project itself, and no claim on its profits.

The $TRUMP memecoin launched three days before Trump’s inauguration in January 2025. About 80% of its supply is held by Trump-affiliated companies, which also collect a fee every time the coin changes hands.

WLFI and USD1 are issued by World Liberty Financial, cofounded in 2024 by the Trump family and business partners. A Trump business entity owns about 60% of the company and is entitled to 75% of net proceeds from token sales.

Trump’s annual financial disclosure shows World Liberty brought him more than $500 million last year, while the memecoin business brought in more than $600 million. Forbes now estimates Trump’s net worth at $6 billion, up from $2.3 billion in 2024.

How do you make a billion dollars from tokens?

Let’s start with the stablecoin, USD1.

As a stablecoin issuer, you take in dollars, hand out coins, and use the dollars to buy US Treasury bonds. Then, you earn interest on Treasury bonds. The more coins you issue, the greater the amount of money you earn interest on. So the main trick is to convince someone to use your stablecoin and hand in the dollars to you, preferably in large amounts.

For USD1, that someone handing in the dollars was Binance, the world’s largest crypto exchange, which had pleaded guilty to US money-laundering violations in 2023. Binance reportedly wrote the computer code underpinning USD1 and promoted it on its platform.

Then, in May 2025, MGX – an Abu Dhabi state fund chaired by the United Arab Emirates’ national security adviser, Sheikh Tahnoon bin Zayed Al Nahyan – invested $2 billion in Binance and paid in USD1. This instantly created $2 billion of interest-earning reserves for the Trump venture, worth an estimated $80 million a year.

Binance today holds 87% of all USD1.

The Securities and Exchange Commission dropped its lawsuit against Binance days after the exchange listed USD1, and in October 2025 Trump pardoned Binance’s founder, Changpeng Zhao. A Wall Street Journal investigation later revealed Sheikh Tahnoon had also secretly bought a 49% stake in World Liberty itself for about $500 million, four days before Trump’s inauguration.

The $TRUMP memecoin required even less effort.

With memecoin, you simply let speculators buy a digital asset that is effectively pure hype packaged as a currency. You make money on every trade. And because anyone, anywhere can buy the coin anonymously, legal experts warn that it operates as a channel for untraceable gifts to Trump and his family.

Some buyers openly spent $148 million in memecoin for seats at a dinner with Trump.

Like most memecoins, $TRUMP collapsed after the initial hype: it now trades at about 98% below its peak.

A Reuters investigation of Trump and his family’s four main crypto ventures – World Liberty, the memecoin business, American Bitcoin and AI Financial Corp – found the family has gained about $2.3 billion since Trump retook office, almost exactly matching the amount lost by more than a million investors.

Without precedent

Some of the crypto regulations issued under Trump are good policy.

For example, the GENIUS Act clarifies the rules of the game for all – something the crypto industry had sought for years.

But all the useful crypto regulation is at risk of being undermined by stories of special favours and institutionalised corruption in Trump’s crypto ventures.

It’s also likely to undermine the US reputation for the rule of law, as Trump’s crypto dealings are without precedent in US history: anyone seeking presidential favour can simply buy the president’s coin.
