Ledger Nano S.

Step 3) Get some elementary education. Anyone who uses Coinbase, or any other exchange or online service as a wallet is an idiot. Those are not meant to be wallets, and you are not in control of "your" coins (unless in cases where they give you private keys but that is not usual for either one).
