The words you are using are very confusing.

You can't "move money into an offline crypto wallet that is not online at all."

If "money" i.e. crypto "currency" is in a crypto "wallet" then it is online. Anyone with the key and an Internet connection can transfer it at any time.

The wording is confusing because to someone who doesn't know how cryptocurrencies work it sounds like you can simply "take the crypto offline and put it into a physical device" as if it was a file. But that's not how it works. The physical key merely contains the actual key for the always-online wallet.
