#CongressTradingBan The investment cryptocurrency wallet (Hierarchical Deterministic Wallet - HD Wallet) is an advanced type of digital wallet used to store cryptocurrencies. It relies on a hierarchical key generation algorithm, where an unlimited set of addresses is created from a single master key, enhancing security and privacy. These wallets provide an easy backup feature through a "Seed Phrase", which usually consists of 12 to 24 words. This technique allows users full control over their digital assets without the need to manage multiple private keys. HD Wallets are widely used in financial and blockchain applications, such as Bitcoin and Ethereum wallets.
