I mean the real purpose is to make money on intelligence-based bets. And what's great is after the fact when everything decrypts you would still get to see the exact timeline of sentiment as it changes, completely undisturbed by the market's existence. This is extremely good data for designing systems to make the correct prediction next time based on things happening in the real world, instead of following the herd and looking for tea leaves in the odds graph. It's the only way to get pure, dollar-weighted sentiment data without the market skewing itself.
