Donald Trump Jr., the eldest son of U.S. President Donald Trump, purchased approximately 350,000 shares of the loss-making social media company Thumzup Media Corp. through a $6.000 million convertible preferred stock private placement arranged by Dominari Securities, valued at over $4.000 million based on the previous closing price. Since January, Thumzup has allocated most of its liquid assets to Bitcoin, currently holding over $2.000 million, and has announced that it will expand to include 6 other crypto assets. This move is part of a recent series of "crypto vault" strategies by the Trump family. [Bloomberg]
