Cold storage is a way to keep cryptocurrency private keys offline, protecting them from hackers. Unlike hot wallets connected to the internet, cold storage removes exposure to online risks.

Methods:

• Hardware wallets – secure USB-like devices.

• Paper wallets – printed keys (less safe today).

• Air-gapped systems – offline computers generating and storing keys.

Benefits:

• Strong security against hacks.

• Best for long-term storage of large holdings.

• Reduces online threats like malware.

Conclusion: Cold storage is one of the safest options for securing crypto assets over the long term.
