To figure out if whales are suddenly moving their BTC or USDT etc from their private/unknown wallets to known exchanges. Or vice versa, if they’re comfortable enough to move a lot back onto their wallets.
Or at least how much money is currently on exchanges vs global crypto cap, plotted onto a chart.
Bonus points if there is a way to know how old the private/unknown wallets are. So for ex if wallets from 6 years ago are suddenly moving BTC to an exchange, vs wallets made e.g. this year.
