This is one of way to be safe in crypto.

Keep devices clean and prevent threats to attack or compromise devices. It is security.

What listed in OP are support tools to increase security but the importance of being carefully on the Internet is key. Don't click on strange links (invitation, sites, whatever); don't download and install strange things; don't install wallets without verification. Tools can not protect us from all dangerous threats on the Internet. If we are careless, we will be caught by hackers someday.

Additionally, the privacy is important too. Some crypto investors carelessly do KYCs for shit bounties or unknowingly disclose their personal identities over the Internet, on third-party sites. They don't know that losing privacy potentially result in losses too.

I meant there are two big things for crypto investors: security and privacy. They have to finish required things to protect their security and privacy concurrently.
