Bitcoin Inheritance Moves into Mainstream Wealth Planning as Affluent Households Hold Digital Assets

Bitcoin inheritance is becoming an increasingly important topic in mainstream wealth planning as more affluent households hold digital assets. A recent report from Barron's highlighted how cryptocurrency is moving into ordinary estate-planning conversations due to the growing number of upper-income Americans investing in Bitcoin and Ethereum. According to Pew Research Center data, roughly 27% of upper-income Americans have invested in cryptocurrencies, compared with 17% in 2021.

The growth of crypto ownership creates an opportunity and a problem for the industry. While Bitcoin can be transferred across generations without requiring a traditional bank to move the asset, ownership alone does not guarantee that an heir will know the asset exists or possess the information necessary to access it.

As larger amounts of Bitcoin remain untouched for years, inheritance planning is likely to become a more visible part of the broader conversation around digital-asset ownership. The problem arises when the crucial access information may exist only on a hardware wallet, recovery phrase, passphrase, multisignature arrangement, encrypted file, or another system understood by one person.

Estimates suggest that approximately 2.3 million to 4 million BTC may be permanently lost, equivalent to approximately 11% to 18% of Bitcoin's maximum 21 million supply. The exact quantity cannot be known because a dormant address does not reveal whether the owner has lost access or is deliberately holding for the long term.
