What Is a Cryptocurrency Wallet?
A cryptocurrency wallet is a digital tool for storing, receiving, and sending cryptocurrencies. Like a bank account, it uses:
- Public Key: Similar to an account number, used to receive funds.
- Private Key: Acts like a password; owning it grants full control over the wallet.
Security Tip: Never share your private key! Wallet safety primarily depends on how the private key is stored.
Hot Wallets: Convenience with Risks
Definition: Hot wallets (or online wallets) operate on internet-connected devices (e.g., phones, computers).
Types of Hot Wallets:
