Cryptocurrency & Blockchain in 2025

Introduction
Cryptocurrency and blockchain technology have transformed the financial landscape, offering new opportunities for investment, decentralization, and security. Whether you’re a beginner or an experienced trader, understanding how cryptocurrency works and its potential can help you make informed decisions. This guide covers everything you need to know about cryptocurrency and blockchain in 2024.



What is Cryptocurrency & Blockchain?

Cryptocurrency is a digital or virtual currency that uses cryptography for security and operates on a decentralized network. Blockchain, the underlying technology, is a distributed ledger that records transactions across multiple computers.

Key Features:

  • Decentralization: No central authority controls transactions.
  • Security: Cryptographic techniques protect transactions.
  • Transparency: Transactions are publicly recorded on a blockchain.
  • Immutability: Once recorded, data cannot be altered.

How Blockchain Technology Works

Blockchain operates as a digital ledger that records transactions in a series of blocks. These blocks are linked using cryptographic hashes, ensuring security and transparency.

How Transactions Work:

  1. A transaction is initiated and broadcasted to a network.
  2. The transaction is verified by network nodes through consensus mechanisms (Proof of Work or Proof of Stake).
  3. Verified transactions are added to a new block.
  4. The block is added to the blockchain permanently.
  5. The transaction is completed and recorded publicly.

1. Bitcoin (BTC)

  • The first and most valuable cryptocurrency.
  • Used as a store of value and digital gold.

2. Ethereum (ETH)

  • Supports smart contracts and decentralized applications (DApps).
  • Undergoing upgrades for scalability and efficiency.

3. Binance Coin (BNB)

  • Used for trading fee discounts on Binance.
  • Supports Binance Smart Chain (BSC) projects.

4. Solana (SOL)

  • Known for its high-speed transactions and low fees.
