Well if I'm the one who's uninformed, you're not telling me anything I don't already know. Yes, I know you can see the transactions they made in that particular token on-chain. You have to get the information about who owns any of those wallet addresses from somewhere else. The chain doesn't tell you anything other than that they sent a token somewhere. Yes the other data is public but that isn't because of any feature of blockchains. The blockchain also won't tell you the actual details of the deals this guy was making or the favors he was calling in, you gotta look through his phone and emails to get that. As I said, it still doesn't paint the full picture because the real money is off-chain and can never be tracked on the chain. No, a USDT or a USDC isn't a real dollar, those movements may or may not represent actual money changing hands.
