The account goes all in. ~$20,000 in a single wager. Running total across the week: ~$34,000. All on YES.
JAN 3 · 1:00 AM
U.S. forces enter Caracas. Operation Absolute Resolve. Maduro captured. The public finds out with the sunrise.

What the tape showed.

Every one of those wagers was public. On-chain. Timestamped. Anybody with the right kind of eyes on the board could have seen the shape of it building — a single account, one contract, one direction, escalating over six days, then a single $20K wager three hours before Caracas.

This is a historical case study, not a verified Piggyback alert. It illustrates why we watch for unusually large trades.

The story here isn't that somebody knew something. The story is that the receipts were sitting in public the whole time, and nobody with skin in the game was watching.

You don’t have to know what they know. You can watch what they do.
