The crypto world is speculating about possible developments from Donald Trump’s sons after enigmatic posts on X.

Donald Trump Jr. hinted at a major development, declaring, “We’re about to shake up the crypto world with something HUGE. Decentralized finance is the future—don’t get left behind.”

This was preceded by Eric Trump’s tweet expressing his newfound enthusiasm for crypto and DeFi, a term for decentralized finance apps.

Eric, who serves as executive vice president of the Trump Organization, tagged several profiles related to his father and brother, suggesting a coordinated effort. This has led many to speculate about a broader Trump family initiative involving cryptocurrencies.

The notion of former President Donald Trump’s involvement isn’t far-fetched, especially considering his previous ventures with NFT collections, which saw a price surge following an incident last month.

However, the crypto community has reacted skeptically. Jameson Lopp, co-founder of Casa Hodl, wryly advised Eric Trump to hold off on any crypto ventures until legal hurdles are clearer. Meanwhile, Gabor Gurbacs, founder of PointsVille, urged Donald Jr. to focus on Bitcoin.

These public declarations come amid a shift in Donald Trump’s own stance on cryptocurrency. Once a critic, he’s now a vocal supporter, even proposing the U.S. could tackle its $35 trillion debt with Bitcoin. He recently promised to build a “strategic Bitcoin reserve” for the United States.
