I'm thinking of getting one of Ledger Blue with firmware 2.1. On their blog post, it says 'developer needs to create a specific Ledger Blue version of the app'. Are the ZenCash team thinking of implementing app for Ledger Blue? --> https://www.ledger.fr/2018/07/02/new-ledger-blue-firmware-version-2-1/
By the way, it's a very good idea to add Ledger to your wallet! This would add to the weight of the coin, since there are a number of investors for whom the possibility of storing coins in similar hardware wallets - this is critical!
