Seed phrase only on paper or metal, only offline.
Never photograph or forward the phrase or keys.
Keep large sums on a hardware wallet.
Download wallets only from official sites and check the address.
Open exchanges only from a bookmark.
Two-factor authentication through an app.
A separate email for the exchange and wallet.
Read what you sign in the wallet and revoke unneeded permissions from time to time.
Send a small test amount to a new address first.
Never give the phrase to anyone: not "support", not a "helper".
