Ledger Nano S has announced support for Ripple and Stratis recently, I think Lisk soon. I have just bought a matched pair (1 for use, 1 for backup) for less than $200USDT - to distribute more amongst my present Ledger Nano and airgapped machine, and paper-wallet (gift-card) regimen. At this stage of the game, hardware wallets seem the pick of the bunch, now beginning to make sense for hodling altcoins.
