Crypto billionaire Justin Sun is buying another $100 million worth of $TRUMP, doubling his total known stake of digital coins tied to President Donald Trump.

Sun, who founded the TRON blockchain and is working to resolve a civil fraud case with the Securities and Exchange Commission, announced the purchase of the $TRUMP token in an X post on Wednesday. Sun said the Trump-linked digital coins will soon be tradeable on the TRON network.

“$TRUMP on TRON is the currency of #MAGA,” Sun wrote.

The $TRUMP token, 80% of which is controlled by the Trump Organization and affiliated entities, has become the centerpiece of the family’s expanding crypto empire.

The $TRUMP token’s code automatically routes a fee from every transaction to wallets tied to its creators. Between January and April alone, those wallets pulled in more than $324 million in trading revenue, according to Chainalysis. The blockchain analytics firm has since ceased tracking this metric, citing other commitments to clients.
