Cryptocurrency

Cryptocurrency is a digital currency (digital money) based on cryptographic processes and usually managed in a decentralised manner via a blockchain.

Hardware Wallet

A hardware wallet is required to securely store private keys for cryptocurrencies offline. The main advantage is its separation from the internet (→ ‘cold storage’), which means it cannot be compromised by malware or remote attacks, unlike software wallets or exchanges.

• Security
  • Private keys never leave the device (source: Ledger Whitepaper)
  • Protection against keyloggers, phishing and remote access
• Independence
  • Full control over your own assets (‘Not your keys, not your coins’)
• Support for multiple signatures and passphrases
  • Additional layers of security possible
• Consistency
  • Independent of compromised computers or mobile devices.

Ledger is one example of a hardware wallet for storing cryptocurrencies securely. It provides a secure environment for managing private keys and signing transactions, ensuring that your digital assets are protected from online threats.

The Ledger Nano S Plus and Ledger Nano X are two popular models that provide robust security features, including secure chip technology and a user-friendly interface.

Hardware for cryptocurrency wallets (for example Ledger Shop)

• Ledger Flex (with a small display and no Bluetooth)
• Ledger Stax (with a large display and a touch screen)
