I have the discontinued Ledger Nano hardware wallet.
Ledger have released new firmware for this for SegWit and to allow splitting BCH.
To perform the update, you have to wipe your keys and re-create them from your 24 word recovery backup. If for whatever reason this doesn't work, your Bitcoins are gone!
This seems a bit extreme/risky to me, because I haven't used my 24 word recovery backup before (what if I got 1 letter wrong in one of the words?).
Just wondering what way I should approach this? Would it be safer to transfer my coins to Coinbase temporarily, update the stick, and then transfer them back? I know I'd be hit for 2 sets of fees, but at least I'd feel a bit safer.
