Opsec tips for those with meaningful crypto holdings but self-custody…
1. Separate device just for smart contract interactions (VMs for the more tech savvy)
2. Hardware wallets ONLY
3. Back up your seed offline, can shamir secret share it and secure in diff locations

4. Separate phone number(s) for all accounts tied to crypto, including PW manager
5. Separate email(s) and passwords for each exchange
6. Authy and Yubikeys - never text based SMS
7. Practice safe aping: revoke contract approval post aping with @DeBankDeFi

8. Don’t wear crypto merch to avoid dollar wrench attack. The comfy @Not3Lau_Capital hoodies stay at home!
9. Use multiple addresses (rip degen score), and multiple wallets
10. No cash deals in person

11. PO box for inbound mail, never send crypto merch to home address because @Ledger might leak your data again
12. Disable multi device on Authenticator apps
13. Destroy old devices, never trade ins (overkill maybe)

14. Don't use paper to back up your seed as your biggest risk might be yourself (accidentally destroying your seed). Use unobtrusive stainless steel. Figure out how to do this.
