Why Choose a Cold Wallet Over a Hot Wallet?
With recent regulatory changes affecting exchanges in certain regions—including temporary closures in parts of China—many investors are reevaluating how they store their assets. While hot wallets (connected to the internet) remain convenient for frequent trading, they inherently carry higher risks.
Here’s why more users are turning to cold wallets like the Ledger Nano S:
- Enhanced Security: Cold wallets are offline, making them immune to remote hacking attempts.
- Dedicated Storage: Designed solely for holding crypto, they eliminate distractions and reduce temptation for impulsive trades.
- Portability & Discreetness: Compact and USB-like in design, they’re easy to store securely.
- Encourages Long-Term Holding: By making transactions less convenient, cold wallets promote “diamond hands” behavior—resisting short-term market noise.
About Ledger: A Leader in Hardware Security
Ledger, a French-based company founded in 2014, specializes in blockchain security hardware. It’s widely recognized as the market leader in hardware wallet sales, with over one million users globally. The brand has earned trust through rigorous security standards, including the use of a certified Secure Element (CC EAL5+), which protects private keys from physical and digital tampering.
Its proprietary operating system, BOLOS (Blockchain Open Ledger Operating System), further strengthens device integrity by isolating applications and ensuring firmware authenticity.
