Self-custody or an exchange account? Compare the failure modes

Ask who can move the asset

In self-custody, possession of the private keys controls authorization. In a custodial account, the service typically controls the on-chain keys and gives you an account claim governed by its terms and systems. The balance may look similar in an app, but the recovery and failure paths are different.

Self-custody reduces dependence on a provider but transfers backup, signing, malware, inheritance, and operational risk to you. Custody can simplify account recovery and support, while introducing platform, withdrawal, policy, and solvency risk.

Use a staged decision

You do not need to move everything to learn. Start with an amount whose loss would be educational rather than destabilizing. Practice backup and recovery. Send a test transaction. Learn to read the explorer. Increase complexity only after the routine is repeatable.

• Can I recover access without an improvised support search?
• Can I verify a transaction without copying instructions from a stranger?
• What happens if the provider, device, or location becomes unavailable?
• Who can help my family understand the plan without already controlling it?

Avoid false certainty

A hardware wallet does not eliminate phishing. A regulated company does not eliminate commercial risk. Diversifying custody can reduce one failure becoming total, but it also adds records and processes to maintain. Document your choices and review them when your value, skill, or circumstances change.
