Some platforms replicate the odds from an Asian site named Pinnacle. When I mention 'Asian sites,' I'm referring to these platforms. some crypto site may appear to operate their own sportsbooks, but in reality, they're trading liquidity on Pinnacle based on actions taken on their platform. So, when you place a bet on one of these sites, it might influence the odds across multiple platforms. It's a nuanced process, but that's essentially how it functions.

Here is probably how it functions and it is called (Liquidity Pooling), some platforms may pool their liquidity or wagers with other platforms or exchanges. When you place a bet on one of these platforms, it can affect the overall liquidity and odds available on that platform, and potentially on other connected platforms and I think that is how it will work.
