Crypto Custody FAQ — Self-Custody vs Exchange, Honestly Compared

What does custodial actually mean?

A third party holds the private keys, and you hold a claim on that party.

Your exchange balance is a database entry representing what you are owed. The assets exist on-chain in wallets the operator controls. Trading moves ledger entries; withdrawing moves the actual asset.

This is not inherently bad — it is how most finance works — but it is a different thing from holding the asset, and the difference only becomes visible when the operator has a problem.

Is self-custody safer?

It removes one risk and adds another.

Removed: counterparty risk. No operator can be hacked, become insolvent, freeze your account, or restrict withdrawals.

Added: key-management risk. No password reset, no support, no reversal. Lose the seed phrase and the funds are gone; expose it and they are taken.

Which is safer depends entirely on which failure you are better equipped to prevent. Exchange failures are dramatic and collective; self-custody losses are quiet and individual. They are not obviously rarer.

What happens if an exchange fails?

You become a creditor in whatever process follows, alongside everyone else. Outcomes have ranged from full recovery after years to near-total loss.

Two things reduce the exposure without requiring full self-custody: not holding more on any exchange than the amount you are actively using, and understanding that protections vary enormously by jurisdiction.

Note specifically that crypto balances are not covered by deposit insurance schemes — see our risk disclosures.

Does "not your keys, not your coins" settle it?

It identifies something real and overstates the conclusion.

Real: an exchange balance is a claim on a company, companies fail, and holders have lost funds when they did.

Overstated: as an unconditional rule it ignores that self-custody transfers risk rather than removing it. Seed phrases get lost. Approvals get signed. Addresses get mistyped.

The honest version is: hold in the model whose failure mode you are actually equipped to prevent — and be aware you may not be equipped for either at large size.

How should I split holdings?

A common and reasonable arrangement:

On an exchange — what you are actively trading, where you want account recovery and support.
In self-custody — holdings you are not actively using, ideally on hardware.
In a burner wallet — anything interacting with unfamiliar contracts.

The point of the split is not purity. It is that a single failure in any one place does not reach everything.

Do exchange security features protect my wallet?

No, and this misconception costs people money.

Two-factor authentication, passkeys, trusted devices and withdrawal allowlists protect your exchange account. They have no bearing on a self-custody wallet: anyone with that seed phrase controls those funds regardless of your exchange settings.

The reverse is also true — a hardware wallet does nothing for your exchange balance.

Is CoinDock custodial?

Yes. CoinDock holds assets custodially, matches orders internally, and requires identity verification. That means real counterparty risk, which our risk disclosures state directly.

Our proof-of-reserves page publishes liability snapshots and states plainly what it is not — it is not a full attestation, on-chain reserve verification, or a completed third-party audit. Treat that page as authoritative over any summary.

We publish this rather than marketing copy because a reader who misunderstands what they are exposed to cannot make a sensible decision.

What should I actually check about a custodian?

What is published about reserves, and what is explicitly not claimed?
What jurisdiction, and what protections exist there?
What controls exist on withdrawals — allowlists, cooldowns, approvals?
Is the operator identifiable and reachable?
Does anything on the site promise returns? That is disqualifying anywhere.

A custodian that states its limits is giving you more to work with than one that claims everything.
