Paperwallet, written seeds on stainless steel, backup inside mail or buying hardware wallet, all these doesn't mean your coins are safe because it still depends on the users themselves, you can't be careless and using a crypto wallet you will eventually do the most stupid thing on day, you can to be a disciplined person to handle your wallet
I agree. In addition to all the rules that were advised above, do not forget about your behavior on the network. You shouldn't tell anyone about the amount of your cryptocurrency, thereby stirring up interest in your funds among hackers.
In addition, your systems must be constantly updated. Your applications must be up to date. And of course, don't turn your back on antivirus software. I would not spare money to purchase a licensed antivirus that regularly updates its antivirus databases.
Your mail should only be used for specific purposes. You shouldn't use it for every need. Likewise, passwords must be complex and have the correct storage.
As for the Chrome browser, its store is full of extensions that have been caught spying on users, which can lead to further loss of funds. I prefer the Firefox browser.
And these are just some ways to keep your wallets safe. It is always necessary to remember that only you are responsible for the safety of your wallets. And how you feel about it will be an indicator of your safety.
