Eric Trump has become a billionaire primarily due to his stake in American Bitcoin, valued at $7.3 billion despite having only two employees. The company holds 2,443 BTC and over 16,000 mining rigs. Both Eric and Donald Trump Jr. are involved in World Liberty Financial (WLFI), which issued a stablecoin backed by $2 billion from UAE investors. The Trump family’s crypto assets and licensing ventures, including international deals, have significantly driven their wealth growth.
