Custody

A cryptocurrency balance is not a file sitting in an app. It is an entry on a shared ledger that will move only for a signature from a specific private key. The wallet is the software that keeps that key and asks you before it signs.

If someone else can sign, they own the coins — regardless of whose name is on an account screen. That is why a seed phrase written on a screenshot, pasted into a chat, or typed into a website is not a backup. It is a second set of keys you no longer control.

Write a seed on paper or steel, store it where a fire and a stranger both have a hard time, and never type it into a browser. Anyone who asks for it, including someone claiming to be Grace Training, is running a theft.

A hot wallet is online because you need it for ordinary activity. A cold wallet stays offline because you do not. An exchange account is neither: it is a claim on a company. You can trade quickly, and you can also discover that withdrawals are paused.

A practical split is boring on purpose. Keep spending and learning size in a hot wallet or a reputable exchange. Keep the amount that would hurt in cold storage, with a seed you have actually tested by restoring a tiny transfer.

Self-custody removes the company’s failure and adds yours. Lost seeds are not recoverable. Start with an amount you can stand to lose to your own mistake, then widen only after the ritual is dull.
