Trump has lined up boxer Floyd Mayweather, "Shark Tank" investor Kevin O'Leary, and NBA player Tristan Thompson to speak at his exclusive dinner for top holders of his meme crypto coin, even as the coin's value has collapsed — bad news for anyone who bought in expecting a payoff.

• The dinner is only open to the top 185 holders of Trump's coin, with a Trump-branded gold watch going to the top four buyers.
• Buying your way into the event used to cost tens of thousands of dollars; after Republicans' poor midterm showing, the coin's price crashed so much that entry now costs a few hundred dollars.
• Melania Trump's own meme coin has also lost almost all its value since launching, down about 99% from its peak.
• A viral exposé this week dug into the Trump family's broader crypto ventures, raising fresh questions about conflicts of interest tied to the presidency.

Outlook: With the coin's value in freefall and scrutiny of the Trump family's crypto dealings growing, expect more attention on potential conflicts of interest rather than any price recovery.
