While many software wallets are very secure, hardware wallets are the safest option. Because software wallets connect to the internet, there’s always a slight chance they can be hacked.
One caveat is that if your cold wallet itself is lost or stolen, it may be impossible to recover your crypto. Always keep your crypto wallet in a safe place!
Some cold wallets, like the Ellipal Titan, do offer recovery options in case you lose your device. If this is something you’re concerned about, research the options before you buy.
