You functionally can't buy insurance on meaningful amounts of Bitcoin. You can convince an insurance company to write you a standard cyberinsurance policy, but the limits on them are far less than the amount of Bitcoin people want to store, and when you have a more bespoke conversation with an underwriter they will say "No no no HELL no."
It is not hard to understand why insurers don't want to write these policies. Bitcoin exchanges die catastrophically in over 20% of exchange-years.
