Although crypto insurance is seeing a rapid growth, the market is still extremely limited in that it only provides coverage to institutions and not individuals. By 'market', we mean reputable insurance market such as the Lloyd's of London and other insurance companies that are subject to regulatory compliance.
You could find online a few unregulated 'insurance companies' offering crypto insurance. Anyone wishing to insure their crypto assets with such insurance companies are advised to check and verify the said companies' credentials and solvency before doing so.
