Understanding Cold Wallets: What They Are and Why You Need One
A cold wallet is a hardware or offline storage solution designed to keep your cryptocurrency private keys secure by never connecting to the internet. This significantly reduces the risk of hacking and malware attacks, making cold wallets a top choice for safeguarding digital assets. Unlike hot wallets connected to exchanges or online applications, cold wallets ensure your private keys remain offline and secure from cyber threats.
