The people I know who've never been scammed in crypto all pretty much have these habits:
1. They use a separate laptop or phone to interact with crypto sites
2. They don't keep all their tokens in one wallet (or on multiple wallets with the same seedphrase)
3. They have stronger security for their most valuable wallets than their day to day trading wallets
Often, that's using hardware wallets or it's multisig/MPC wallets
4. They bookmark their favorite crypto sites instead of relying on Google to find them
5. They never trust an email or DM. They go directly to the source when they need to do something, not externally presented links
6. They revoke their approvals on EVM chains using tools like Revoke Cash or Etherscan
6. They do their own research on protocols and don't blindly deposit funds into untested protocols
7. They double check the addresses they send to, and don't copy/paste wallet addresses from Blockscanners
FINALLY, 8. they take their time when transacting and do it when they're at their best.
They don't rush, or transact while drinking, or under the influence of drugs or when they're tired.
Staying safe in crypto doesn't have to be complicated. You just have to be consistent and do what works.
