Use the coin type numbers defined in SLIP0044: https://github.com/satoshilabs/slips/blob/master/slip-0044.md HDCoinType has been removed, to break old code on purpose. If possible, the new SLIP0044CoinType should be used instead. For backwards compatibility, the old HDCoinType values have been kept as LegacyCoinType.
