Yes, once you own a sizeable amount of cryptocurrency, you should get a hardware wallet for cold storage of your crypto coins offline. You need to protect your confidential data and the access to your funds in case the crypto exchanges where you buy or sell your cryptocurrency get hacked.

The Ledger Wallet, made by a team of leading cryptographers in France, is a popular hardware wallet. With Ledger Nano S, secrets like private keys are never exposed: sensitive operations are isolated inside your hardware wallet within a state-of-the-art Secure Element, locked by a PIN code. Transactions can’t get tampered with, they are physically verified on the device’s embedded screen with a simple press of a button.

The Ledger Wallet stores Bitcoin (BTC), Bitcoin Cash (BCH), Bitcoin Gold (BTG), Dash (DASH), Ethereum (ETH), Ethereum Classic (ETC), Litecoin (LTC), Neo (NEO), Ripple (XRP), Stellar (XLM) or Zcash (ZEC) offline among others. You can store up to five different cryptocurrencies on one Ledger Wallet.

Important advice: never buy a hardware wallet from resellers or off eBay — to avoid scam artists, only buy it directly from Ledger Wallet itself!
