#CryptoSecurity101 Setting up "Crypto Security 101" is a broad topic, but I can provide a comprehensive overview of the fundamental principles and best practices for securing cryptocurrencies.

Here's a breakdown of essential crypto security concepts, presented in a structured "101" format:

Crypto Security 101: Fundamentals for Protecting Your Digital Assets

Cryptocurrency security is paramount in a world where you are your own bank. Understanding these basics will significantly reduce your risk of loss.

1. Understanding the Basics: Custody and Keys

* Self-Custody vs. Third-Party Custody:

* Self-Custody: You hold your own private keys. This gives you full control but also full responsibility for security. This is generally recommended for experienced users and larger holdings.

* Third-Party Custody (Exchanges, etc.): You trust an exchange or other service to hold your private keys. Convenient, but introduces counterparty risk (e.g., hacks, insolvency of the platform).

* Private Keys: The most critical component. A private key is a secret number that allows you to spend your cryptocurrency. Whoever has the private key controls the crypto.

* Public Keys/Addresses: Derived from your private key. These are what you share with others to receive cryptocurrency.

* Seed Phrase (Mnemonic Phrase): A series of 12 or 24 words that can regenerate your private keys. It's your ultimate backup. Treat your seed phrase like the crown jewels.

2. Wallet Types: Choosing the Right Storage

Wallets don't "store" crypto; they store your keys.

* Hot Wallets (Online/Connected):

* Description: Connected to the internet. Convenient for frequent transactions.

* Examples: Exchange wallets (Coinbase, Binance), software wallets (MetaMask, Exodus), mobile wallets.

* Security Risk: Higher risk of hacking due to internet connectivity. Use for smaller amounts or active trading.

* Cold Wallets (Offline/Disconnected):

* Description: Not connected to the internet, providing superior security.

* Examples:

* Hardware Wallets: Physical devices (Ledger, Trezor, Keystone).
