Transaction data of coins like BTC that adopt the UTXO model are open, viewable and traceable. Using the same address for too many times will reduce your privacy, and better anonymity and privacy can be achieved by using sub-addresses. When you’re receiving asset, there’s no need to worry about too many addresses to manage because ViaWallet is an HD (hierarchical deterministic) wallet, with your mnemonic phrase, you have full control over all of your sub-addresses.
Currently, ViaWallet supports address switching for 11 coins, respectively, BTC, BCH, BSV, LTC, DASH, DOGE, FCH, DCR, ZEC, DGB and LBC.
