Introduction
While cloud storage has diminished traditional roles of USB flash drives, they've emerged as a secure cold storage solution for cryptocurrencies. Acting as modern-day digital safes, USB devices offer offline wallet storage, protecting your private keys from online threats.
Why Hardware Wallets Matter
Notable Cryptocurrency Hacks
Cryptocurrency exchanges and hot wallets are frequent targets of cyberattacks, resulting in irreversible losses:
