Backup Funds Air Gapped Tutorial: Secure Your Crypto in 7 Steps

What Is an Air-Gapped Backup (And Why Your Funds Need One)

An air-gapped backup is an offline storage method that physically isolates sensitive data like cryptocurrency wallets or financial information from internet-connected devices. This creates an impenetrable barrier against hackers, ransomware, and remote attacks. For funds requiring maximum security, air-gapped systems are the gold standard.
