The whole betting statistics were a big disappointment for a mankind.

Also in my country (it is in Europe), this event break history records in betting. Funny thing is, that even though every win prediction was on side of Biden, the most of the people here bet on Trump (about 70% of bets value). So I guess most of the bettors here do betting for fun, with no knowledge of the topic.

Also it was funny to observer the prediction market. At the early times of election, when the immediate results were in favor for Trump, the prediction market change the sides to reflect that. In other words people totally panicked and no longer trust in the pre-determined win of Biden. To be honest I was also quite panicking, because I though that prediction market is used by competent people.

So this event was a decent lesson about why people keep losing money via betting.

One more funny thing I noticed is: at freebitco.in was odd on Biden 1.99 in the last hours. While the conventional offices has something like 2.2 on Trump. So there was a room to bet on both and win money no matter who wins the election (however there is still few issues: BTC/fiad volatile price, any office can cancel the bet etc., so I have not tried that)
