I would like to suggest

Encrypted vpn. Use one everytime you log in.
Use an anit virus. I use eset as it is Australian.
NEVER store cxryptos on a computer or exchange. Always in cold storage.
Never keep private keys online.
Use encrypted email servers. Even if you have  to pay for them. Countermail has a usb service. Recommended.
Be familiar with pgp.
Use long and complex passwords.
Use a password keeper. Encrypted with 2fa.
