Your Bitcoin is your money and it needs to be kept secure. There are layers of security beneath the surface that protect your private Bitcoin key, or combination, and keep it safe. Some people store their keys in hot wallets. A hot wallet means the keys are held on a device that's connected to the internet, which can be vulnerable to security threats. While others prefer a more secure way to go called cold storage. That's the system that we use. Cold means that the key is not connected to the internet but stored in an actual physical space, which reduces the risk of hacking with even more layers of security. Cold storage safeguards have been protecting money since before cryptography was invented and will continue to do so for years to come. That's secure. Bitcoin secure.
