Hardware wallets are considered the safest of all wallets today,
Thats not true at all. Hardware wallets just offer the highest user friendliness while keeping a pretty high protection against theft of your coins. There are many more secure ways to store your coins, but basically all of them require to just store the coins and not have outgoing transactions.
We only have a hardware wallet and software wallets. If comparing them, what is wrong with saying hardware wallet is more secure? And how to use a secure wallet depends on how we use it?, not just having a hardware wallet means that our assets are automatically safe.
Apart from using these two wallets, would you happen to have a way to store our assets more securely? Can you share? I used software wallets for a while, then switched to hardware wallets, and I really feel my assets are incredibly safe compared to software wallets.
