I get that hard wallets are the way to go, but when (and where) will we exactly see these pop up? I have the Ledger Nano S but don't they need to develop the app interface to allow these coins to be on the hard wallet? For example, I believe my Ledger holds 4 currencies maximum. So I need to have BTC on my Ledger and 1 open slot for another currency? So BCC can be there? This is all just really weird and vague 😄
