Always Use Hardware Wallets, and Never leave large amounts of crypto on exchanges, with what happened with FTX, we should all learn something from it
We have seen a lot of influencers posting screenshots of millions of dollars running on a single trade
we have seen some posting a 10,000,000 $USDC balance
this is not bad, but you shouldn't leave such an amount of money on CEX and also, posting such pictures that could be edited, could attract some individuals and organizations that you don't want
Use a hardware wallet like a Ledger or Trezor for maximum security.
These wallets store your private keys offline, minimizing the risk of hacks.
