Crypto Asset Security Storage Guide: Cold Wallet Recommendations and Selection Tips

Why Use a Cold Wallet to Protect Your Crypto Assets

Many investors have lost assets due to exchange hacks or account breaches. Unlike hot wallets connected to the internet, cold wallets are physically isolated storage devices, with private keys managed entirely offline, effectively preventing malicious software and hacker intrusions. If you hold a large amount of cryptocurrency, using a cold wallet for storage is a necessary measure to safeguard your assets.

The Core Principle of Cold Wallets at a Glance

Many people mistakenly think that a wallet is a place to store cryptocurrencies. In reality:

• All crypto assets are stored on the blockchain network, not inside the wallet
• The wallet only holds a pair of keys: the public key (your blockchain address) and the private key (transaction authorization tool)
• Only the corresponding private key can access and transfer your assets
• Private keys must be kept absolutely confidential; if leaked, assets are at risk

The role of a cold wallet is to securely store these private keys in a completely offline environment. Since it cannot directly connect to DApps, it is most suitable for long-term holding. When a transaction is needed, users transfer funds to a hot wallet to perform operations.
