Hello everyone,
What would happen if I had some bitcoins in a Nano S wallet and someday ledger decides to drop the project. Would I be able to still use my wallet somehow if I had my seed?
Yes you can import it in a wallet which is compatible with that seed. I know electrum is, so you can restore your wallet through your seed in Electrum which supports BIP32 and BIP39. I am not sure but even Mycellium supports this, so yes there are a few options.
