Our take

Ledger has grown into one of the world’s largest hardware wallets for digital assets since its 2014 inception, with well over 6 millions of devices sold across the globe. By offering physical devices to store private keys, customers are able to secure their digital assets offline.

The company is attempting to support the continued growth of the crypto eco-system by offering cryptocurrency owners an alternative to storing their assets on an online exchange. There, a simple password breach could cause untold damage.

Ledger’s hardware solution has proven popular with investors, seeing them receive huge funding from 10T Holdings, Cathay Innovation, and Draper Associates to name just a few.

Keen to move on and ensure against any recurrence, Ledger has since secured even more investment, and formed astute partnerships with other big names in the Crypto world, including an integration with Coinbase.
