### Wallet
Hierarchical Deterministic Key Generation
-----------------------------------------
Newly created wallets will use hierarchical deterministic key generation
according to BIP32 (keypath m/0'/0'/k').
Existing wallets will still use traditional key generation.
Backups of HD wallets, regardless of when they have been created, can
therefore be used to re-generate all possible private keys, even the
ones which haven't already been generated during the time of the backup.
HD key generation for new wallets can be disabled by `-usehd=0`. Keep in
mind that this flag only has affect on newly created wallets.
You can't disable HD key generation once you have created a HD wallet.
There is no distinction between internal (change) and external keys.
