This is for those who use wallets with cheap transaction fee, such as ethereum based wallets.
There are some who cannot yet afford to purchase a hardware wallet. On that note, i have a suggestion on how your wallet can be safe from hackers. I have always noticed wallets that get easily hacked are those that are subject to public view.
Try as much as possible to have a separate cold wallet address that you do not copy and paste the private key, and neither do you share the address with anyone. You can use it to store most of your valuable coins.
Even if you want to transfer any coin or token to an address belonging to another person, first transfer it to your public wallet before sending it out.
lots of security options available for every person to handle their wallet to be more secured and safely but in sometimes we can not sure about what is going on so probably our wallet is also hack by someone but what we can do is to make the possible ways of security available given from the side of the wallet
