related https://github.com/spesmilo/electrum/issues/8202 For a HD wallet, instead of checking the first 10 addrs + 10 additional random ones, we now check the first 10 addrs + 10 random used addrs + 10 random unused addrs. Checking unused addresses is useful to prevent getting money sent there, and checking used addresses is useful to inform people of already lost money.
