Best Crypto Exchanges: Your Ultimate Review with Pennington Capital

Welcome to the Best Crypto Exchanges section of Pennington Capital. Crypto exchanges are digital platforms that enable buying, selling, and trading cryptocurrencies like Bitcoin, Ethereum, and altcoins, offering access to a $2.5 trillion market as of September 2025. With Bitcoin reaching an all-time high of $124,500 on August 14, 2025, and global trading volume exceeding $134 billion daily, exchanges like Coinbase, Kraken, and Gemini stand out for security, low fees, and user-friendly features.

In the U.S., regulatory clarity from the SEC and FinCEN has boosted adoption, with 70 million users on platforms like Coinbase and Binance.US, though tariffs (0.4pp inflation) and a 4.00-4.25% federal funds rate impact transaction costs.

This guide, informed by trusted sources like Investopedia, Forbes Advisor, and NerdWallet, reviews the best crypto exchanges in simple terms. Whether you’re starting with $100 in BTC or trading altcoins, we’ll cover the essentials, comparisons, and pitfalls to help you select the right exchange.

1. Best Crypto Exchanges Basics: How They Work

Crypto exchanges are online marketplaces where users trade digital assets, similar to stock brokers but for cryptocurrencies.

• What They Are: Platforms like Coinbase or Kraken allow buying/selling crypto with fiat (USD) or other coins, with features like staking, NFTs, and advanced charts. Example: Buy $100 of BTC on Coinbase at $124,500/BTC, paying 0.5% fee ($0.50).

• How They Work: Create an account, verify identity (KYC), deposit fiat/crypto, and execute trades (spot, futures). Exchanges hold assets in wallets; users can withdraw to personal wallets. Example: Gemini’s 160+ coins and staking yield 5% on ETH.

• Key Features:

  • Fees: Maker/taker 0-0.4% (Kraken), spreads 0.5-1% (Coinbase).

  • Security: Cold storage, 2FA, insurance (Coinbase’s $320 million fund).

  • Coins: 100-4,200+ (MEXC leads with 4,200).

  • Tools: Charts, staking (5-10% yields), mobile apps (Robinhood’s intuitive interface).

• Price Drivers: BTC at $124,500 drives volume ($134 billion daily); Fed rate (4.00-4.25%) and tariffs (0.4pp inflation) affect fiat deposits.

• Key Players: Centralized exchanges (CEXs like Binance), decentralized (DEXs like Uniswap), regulators (SEC, CFTC).

Pro Tip: Start with a regulated U.S. exchange like Coinbase for beginners to ensure KYC and insurance.
