It depends on what you need it to survive. Coinbase Custody runs single custodian custody, which has a single point of failure: one institution's failure can reach your bitcoin. Proof of Custody scores it 61/100 as of 2026-02-18. Exchange / single custodian account is a good fit for first purchases and small balances, where losing the amount would sting but not change your life, and the wrong choice for life-changing amounts: you are an unsecured creditor in the failure case, and every era of our incident registry includes this exact loss. The score is an editorial judgement; the facts to check are the custody model, the single point of failure and the incident history below.

Coinbase Custody's custody insurance is not publicly disclosed.
Coinbase Custody uses a single custodian model and scores 61/100 in our independent review, including 70/100 on custody security. One institution can move funds, which is a single point of failure. Safety depends on your priorities; see the full score breakdown above.
Coinbase Custody's custody insurance is not publicly disclosed in a form we can verify. Where it exists, custody insurance covers specific named events up to shared limits and does not cover price loss. Confirm coverage in writing before relying on it.
Because Coinbase Custody holds custody through a single institution, recovery in a failure would run through that institution's bankruptcy or resolution process and depends on whether assets were segregated and properly titled. This is the concentration risk of single-custodian models.
Coinbase Custody does not advertise a dedicated inheritance or beneficiary feature in the data we track. Confirm current options with the provider, since custody inheritance handling changes.
