yoooo i actually personally do NOT want people knowing what i buy

let me choose to make this private or public like venmo come on

otherwise doing my large volume trades in other wallets

building @privy, ex-farcaster | surfing @ venice, ca | eating @ gjusta / gjelina | “lucky me, lucky mud” 🤠

Hyperliquid

why would you notify the entire platform about my trades but not show my casts to all of my followers

Because web3 still thinks in money terms. 
As far as we have come from the money aspect of this it's still tied to every conversation and people wanna follow trades just as much as your posts
But I definitely agree. There should be a privacy option there. That was the original point of the whole space, privacy.
