Just days ahead of his return to the White House, President Trump and his wife Melania launched a pair of meme coins that have skyrocketed in value and earned them billions of dollars, at least on paper.

Separately, shares of Trump’s other publicly traded eponymous entity, Trump Media & Technology Group, dropped more than 10% in the first day of trading following Trump’s inauguration.
