The Trump family openly makes money in the cryptocurrency industry through various means. Rumors suggest they plan to learn from MicroStrategy to finance the purchase of Bitcoin, but this was later denied.
The Trump family makes money through:
1. Issuing stablecoin $usd1
2. Issuing meme coins $TRUMP and $MELANIA
3. $WLFI token sales
4. Bitcoin mining and NFTs
They are making a fortune; indeed, being president is a good business.
