Maybe I'm wrong to understand your topic about 'Financial Betting', of course I am a layman in this matter, As far as I know, as a layman, all types of Crypto/Bitcoin based gambling, etc., have always offered Financial bets.

However, the financial meaning if it is explained is quite a lot and broad, I mean like this, financial in the form of how the gambling site you mean, forecasting, investing, lending, trading, and many other types of finance, essentially dealing with finance.

Of course, for me the layman, the definition of finance on gambling sites is broad, can you explain what kind of finance is.
