When poring over your Bitcoin transaction history, you may notice your wallet address has changed over time. This might make new crypto users nervous, but it’s just a security feature. Many wallets and exchanges automatically generate a new address for every transaction, and most crypto wallets are actually able to manage hundreds of Bitcoin addresses simultaneously. Any previously used addresses remain permanently connected to your wallet and can still be used to send or receive funds. However, continuing to use them could compromise your privacy and make your blockchain activity more easily tracked. It’s worth noting that these address changes only happen with cryptocurrencies on the Bitcoin blockchain, such as Bitcoin Cash (BCH), Litecoin (LTC) and Dogecoin (DOGE).
