Since you paid a hefty $24 transaction fee, expect it to arrive sooner or later. Most likely not more than 5 hours or so.
Good move on investing on a Ledger Nano S though. Security should always be a priority

$24 isn't hefty. Its the price of a nice lunch or lousy dinner in a higher cost of living area in the US

I will plug my Nano S in 3 hours and check. Coinbase had a message on their 'support' site saying that BTC transfers
are delayed 'a couple hours'.
From my reading, it seems like cold storage on the Ledger is a good way to ensure that I would get the Segwit2x fork. Does that sound about right?
