About Meanwhile Insurance Bitcoin (Bermuda) Limited
Meanwhile is a life insurance carrier licensed and regulated by the Bermuda Monetary Authority, offering the first-ever life insurance policies denominated in Bitcoin. Their core product is a whole life policy that allows policyholders to maintain their investment in Bitcoin while gaining the benefits of life insurance, such as tax-efficient growth and liquidity. Policyholders can grow their Bitcoin tax-free, borrow up to 90% of the policy's value after two years, and secure a guaranteed death benefit paid in Bitcoin to their beneficiaries. This structure aims to simplify inheritance planning by handling the transfer of Bitcoin directly, eliminating the need for complex hardware wallets or custodial setups. The company emphasizes a blend of traditional insurance values—guaranteed payouts, conservative investment strategies, and disciplined risk management—with modern innovation, using AI-powered underwriting for transparency. While affiliated with US-based Meanwhile Incorporated, all insurance business is conducted exclusively in Bermuda.
