Cryptocurrency storage solutions fall into two primary categories: hot wallets (connected to the internet) and cold wallets (offline storage). This guide explores their key differences, advantages, and ideal use cases to help you make informed decisions about securing your digital assets.
Understanding Cryptocurrency Wallets
As blockchain adoption grows, choosing the right wallet becomes critical for safeguarding digital assets against cyber threats. Wallets don't physically store coins but manage private keys that control access to funds on the blockchain.
