A cryptocurrency wallet is a tool that stores the private keys needed to access and manage your digital assets on the blockchain. Contrary to common belief, wallets don't actually 'store' your crypto — your assets live on the blockchain. The wallet stores the keys that prove ownership.
Hot Wallets (Software)
Hot wallets are connected to the internet, making them convenient for frequent transactions.

Cold Wallets (Hardware)
Cold wallets store private keys offline, providing maximum security.

Pros: Immune to online attacks, ideal for large holdings Cons: Cost $50-$250, less convenient for frequent trading
Seed Phrases
When creating a wallet, you receive a 12 or 24-word seed phrase. This is the master key to your funds. NEVER share it with anyone, NEVER store it digitally, and NEVER enter it on any website. Write it on paper and store it securely.
