Learn About Cryptocurrency Platforms

Exchanges, wallets, and DeFi — how they work, when to use them, and how to stay safe.

Overview of cryptocurrency platforms including exchanges, wallets, and DeFi
From centralized exchanges to DeFi protocols — understand the tools before you trade.
Key takeaways
  • CEX vs DEX: CEX = convenience & liquidity; DEX = self-custody & on-chain transparency.
  • Wallet choice matters: Custodial = simpler; self-custody = control + responsibility.
  • Security first: 2FA, hardware wallets, phishing awareness, and seed phrase hygiene.

Centralized & Decentralized Exchanges

Centralized exchanges (CEX): onboarding is simple, deposits/withdrawals are fast, and order books are deep. You trade inside the exchange’s system and rely on its custody.

Decentralized exchanges (DEX): connect a wallet and trade via smart contracts. You keep your keys, but you’ll pay gas fees and need to understand slippage and approvals.

Wallets: Custodial vs Self-Custody

  • Custodial: Email/password recovery, integrated fiat ramps, simpler UX. Trust the provider.
  • Self-custody: You control keys and recovery phrase. Use a hardware wallet for larger balances.

DeFi Basics: Lending, Staking, Liquidity

DeFi protocols let you lend/borrow, stake to help secure networks, or provide liquidity to earn fees. Yields fluctuate; smart-contract and market risks apply.

Fees & Execution Tips

  • Compare maker/taker fees on CEX and gas + swap costs on DEX.
  • Batch actions when possible; avoid peak network congestion.
  • Use limit orders on CEX and reasonable slippage on DEX.

Security Checklist

  • Enable 2FA (authenticator app), whitelist withdrawal addresses.
  • Store seed phrases offline; never share them.
  • Verify URLs, revoke old token approvals, and beware impersonation scams.

Check audits, TVL trends, team reputation, and transparency. Start small and diversify.
