Crypto 101: Everything You Need to Know Before You Invest

What is Cryptocurrency?

Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments, cryptocurrencies operate on decentralized networks using blockchain technology — a public ledger that records all transactions.

Popular Cryptocurrencies to Know

  • Bitcoin (BTC): The first and most valuable cryptocurrency. Often referred to as “digital gold.”

  • Ethereum (ETH): Known for its smart contracts and decentralized applications (dApps).

  • Binance Coin (BNB): Powers the Binance exchange and is used for trading fee discounts.

  • Solana (SOL), Cardano (ADA), and Polkadot (DOT): Emerging projects with unique use cases and strong communities.

How Does Crypto Work?

Cryptocurrencies are powered by blockchain, a decentralized system spread across many computers. Each transaction is verified by network participants (miners or validators), then added to a “block” and permanently recorded. This structure makes crypto secure, transparent, and resistant to fraud.

Why Do People Invest in Crypto?

  • High Growth Potential: Cryptos like Bitcoin have seen exponential gains since their inception.

  • Decentralization: Many are drawn to the idea of financial systems without central authority.

  • Portfolio Diversification: Crypto can act as an alternative asset class.

  • Innovation: Blockchain technology is disrupting multiple industries, from finance to gaming.

Risks to Be Aware Of

  • Volatility: Crypto prices can swing dramatically in short periods.

  • Regulatory Uncertainty: Laws vary by country and may change rapidly.

  • Security: Without proper storage, digital assets are vulnerable to hacks and theft.

  • Scams: Be cautious of pump-and-dump schemes, rug pulls, and fake exchanges.

How to Get Started

  1. Choose a Reputable Exchange: Start with platforms like Coinbase, Binance, or Kraken.

  3. Start Small: Don’t invest more than you can afford to lose.

  5. Monitor the Market: Use tools like CoinMarketCap, TradingView, or crypto news sites to stay updated.
