What Is A Crypto Wallet

A crypto wallet is like a digital version of your real-life wallet — but instead of holding cash and cards, it stores the tools you need to access, send, and receive cryptocurrency.

Here’s the breakdown: 

 1. What it actually stores Not your coins directly — Your coins live on the blockchain (a public digital ledger). What the wallet holds is your private keys — secret codes that prove you own and can use your crypto. It also has public keys and wallet addresses — like your bank account number, which you can share to receive funds. 

2. Two main types of wallets: 

 A. Hot wallets – connected to the internet Examples: mobile apps, web wallets, desktop software. Pros: Convenient, fast access. Cons: More vulnerable to hacking. 

B. Cold wallets – offline storage Examples: hardware wallets (USB-like devices), paper wallets. Pros: Very secure against online attacks. Cons: Less convenient for frequent transactions.

 3. How it works in practice: 

 Receiving crypto: Someone sends it to your wallet address.

 Sending crypto: 

You use your private key to sign a transaction, telling the blockchain, “Yes, I’m the rightful owner—move these coins.”

 Security tip: 

If you lose your private key (and have no backup), you lose access to your crypto permanently. 

💡Simple analogy: 

 Blockchain = a giant public bank ledger. 

 Public address = your account number (you can share it).

 Private key = your account PIN (keep it secret). 

 Wallet = your bank card that stores the PIN and lets you access the account.

What Is A Crypto Mining

Crypto mining is the process of using computers to help run and secure a cryptocurrency network — and getting rewarded with new coins for doing it. Let’s break it down simply:

Let's break it down: 

Why mining exists: Cryptocurrencies like Bitcoin run on a decentralized network (no bank or central authority).

The network needs people (miners) to: 

Validate transactions – make sure no one is cheating. 

Add transactions to the blockchain – the permanent public ledger. 

Keep the network secure – by making it hard for bad         actors to alter data.

2. How mining works (step-by-step)

1. Transactions happen — People send crypto from one wallet to another.

2. Miners gather transactions into a “block.”

3. Miners solve a puzzle — A very hard mathematical problem called a cryptographic hash.

This requires powerful computers doing millions of guesses per second.

This is called Proof of Work (PoW).

First miner to solve it gets to add the block to the blockchain.

Reward — That miner earns newly created coins plus transaction fees.

Types of mining:

ASIC mining – Specialized machines built just for mining. 

GPU mining – Uses powerful graphics cards (common for altcoins). 

 CPU mining – Regular computer processors (mostly obsolete). 

Cloud mining – Renting mining power from someone else’s hardware.

Challenges of mining:

High electricity use — Mining consumes a lot of power. 

 Expensive equipment — Good mining rigs aren’t cheap. 

 Competition — More miners = harder puzzles.

 Not all coins are mineable — Some use other systems like Proof of Stake instead.

💡 Simple analogy:

Mining is like a giant math competition where thousands of people are racing to solve a puzzle. The winner gets the prize (new coins) and the right to write the next page of the blockchain “history book.”
