Everything You Need to Know About Cryptocurrency: Basics, Wallets, Exchanges & Security (2025 Guide)

Crypto 101: What You Really Need to Know Before You Start

A practical, no-jargon primer on assets, custody, fees, and security—so you can avoid the most common mistakes.

Introductory guide to cryptocurrency basics, wallets, exchanges, and security
Understand the basics—assets, custody, and risks—before you buy your first crypto.
Key takeaways
  • Know what you own: Coins secure networks; tokens ride on existing chains with different purposes.
  • Custody is everything: Exchanges are easy but custodial; self-custody gives control—protect your keys.
  • Safety first: 2FA, hardware wallets, whitelists, and cautious approvals prevent most losses.

Crypto Basics in 3 Minutes

  • Blockchain: A public ledger that anyone can verify. Transactions are bundled into blocks and secured by consensus.
  • Coins vs tokens: Coins (BTC, ETH) are native; tokens (ERC-20, SPL) represent utility, governance, or claims.
  • Stablecoins: Pegged to fiat (e.g., USD). Useful for payments and hedging volatility—still require counterparty risk checks.

Wallets & Custody: Your Options

  • Custodial (exchange/app): Email + password; easy recovery; platform holds keys.
  • Self-custody (software): You hold keys/seed; convenient for daily use; protect device and backups.
  • Hardware wallet: Best for larger balances; signs transactions offline; keep seed phrase offline.

Rule of thumb: trade on exchanges, store long-term in self-custody/hardware. Never save your seed online.

Exchanges: Fees, Liquidity & Risks

  • Liquidity: Tighter spreads and deeper books reduce slippage on bigger platforms.
  • Fees: Watch maker/taker, funding, withdrawal, and FX spreads.
  • Compliance: KYC/AML and regional rules affect availability and limits.
  • Counterparty risk: Diversify platforms; enable withdrawal whitelists and alerts.

Security Checklist

  • Enable 2FA (authenticator app), disable SMS if possible.
  • Use a hardware wallet for long-term holdings.
  • Set withdrawal whitelists and address book approvals.
  • Verify contract addresses and signer prompts; avoid blind permit()/setApprovalForAll.
  • Beware of phishing—bookmark official domains; never share your seed.

Build a Simple Starter Plan

  1. Pick 1–2 assets you understand (e.g., BTC, ETH) and size positions conservatively.
  2. Automate buys (DCA) to reduce timing risk; avoid leverage at the start.
  3. Set rules for adding/reducing exposure; keep an emergency cash buffer.
  4. Review quarterly: Fees paid, allocations, and security posture.

FAQs

What’s the safest place to store crypto?

For long-term holdings, a hardware wallet with an offline, written seed backup stored securely.

How much should I start with?

Only what you can afford to hold long term. Many beginners use small, regular purchases to learn without big risk.

Are stablecoins risk-free?

No. Check the issuer’s reserves, audits/attestations, and the chain you’re using. Treat them as cash-like but not equivalent to a bank deposit.
