Understanding Cryptocurrency Wallets
Cryptocurrency wallets aren't "digital safes" as commonly misunderstood. Instead, they're software tools or physical devices that store public and private keys to access blockchain assets. These keys—long alphanumeric strings—enable sending/receiving digital currencies. Wallets broadly fall into two categories:
Hot Wallets
- Always connected to the internet
- Designed for frequent transactions
- Accessible via multiple devices
Cold Wallets
- Operate offline
- Prioritize long-term storage
- Require physical connection (USB/QR) for transactions
