Ledger keys: the strengths of the physical wallets Ledger
A cold wallet - or offline wallet - is the best option if you want to secure your cryptocurrencies . Software solutions (often called hot wallet S or online wallet ) store your private keys on a device connected to the Internet, which makes them more vulnerable to computer attacks. The Ledger keys , on the other hand, retain these offline sensitive data, which considerably limits the risk of hacking. On the other hand, they involve a manual connection to the less accommodating device for regular transactions. Most investors available on both, an online wallet for regular transactions and interactions with decentralized applications and an offline portfolio for more secure long-term storage.
