The key to inheriting virtual currency heritage lies in planning ahead and safely passing access credentials. 1. Virtual currency inheritance refers to digital assets such as Bitcoin and Ethereum left behind after an individual's death. The ownership of the assets depends on private keys or mnemonics. If there is no certificate, the assets will be permanently locked. 2. Although most countries do not have special laws, virtual currencies are generally regarded as legal property of individuals and are inheritable.
