Introduction
If you want to use or invest in cryptocurrency, you must understand crypto wallets. Without a wallet, you cannot store, send, or receive digital assets like Bitcoin or Ethereum.
But here’s the important part: wallets don’t actually store coins — they store private keys.
What is a Crypto Wallet?
A crypto wallet is a digital tool that allows you to interact with blockchain networks. It stores your private keys, which give you access to your funds.
How Crypto Wallets Work
When you receive crypto:
- The transaction is recorded on the blockchain
- Your wallet uses your private key to access it
Without the private key → no access.

2. Cold Wallets (Offline)
