Cardano (ADA) HD wallets
Cardano now supports UTXOs (like bitcoin). We should support syncing all UTXO addresses using the public root key. Note: IOHK does not yet robustly support getting your public root key from ADA wallet (e.g. Yoroi, Daedalus).
Preferably implement CEX sync (CryptoTrader has done this), or implement support for ingesting the CSVs they export. Expecting people to translate the CSVs themselves is dangerous. (Particularly since uploading a second fixed copy would result in duplicate data).
