Introduction

In the ever-evolving world of cryptocurrencies, security is paramount. With the rise in cyberattacks and cryptocurrency thefts, investors are increasingly turning to cold wallets to protect their digital assets. This article focuses on three of the most popular cold wallets on the market: Ledger, Trezor, and D'CENT.

What is a Cold Wallet and What is it Used For?
