There is a limited amount of usage you can get out of something like this. For example back when TRX was getting heavily d umped for a good 2 week period. You could actually find the largest TRX wallet that was dumping it, and you could tell that it was a systemic dumping based on how much TRX the wallet was selling. And then all of a sudden the selling stopped on that wallet, and didnt move for like a good 2-3 days, that could be interpreted that whatever dumping plans the whales had is now over and it safe to buy back in. Something like that could work, but its highly situational.
