A bettor profited close to $500,000 by predicting the removal of Venezuela's president shortly prior to it was officially announced, leading to inquiries about potential gains made from confidential information of the event.
Bets placed on the crypto-platform, an online prediction market, that the leader would be removed from office by the end of January surged in the hours before President Donald Trump declared on Saturday that the president had been taken into custody.

The identity is unknown. The user had only a blockchain identifier for identification.
Market statistics shows that users assessed the probability of the president's removal at just 6.5% in the midday period of the prior Friday.
However the odds had jumped to 11% by shortly before midnight and spiked dramatically in the first hours of Saturday, pointing to a sudden change in market sentiment just before the official statement was made.
"That trade has all the characteristics of a transaction based on inside information," stated an industry expert.
Several of other platform users also earned significant sums from similar wagers.
Some lawmakers are starting to take note.
Proposed legislation put forward on Monday seeks to ban federal workers from participating on forecasting platforms if they have "confidential government knowledge" related to a wager.
