Cryptocurrency has evolved far beyond Bitcoin. In 2025, dozens of digital assets play crucial roles in payments, smart contracts, decentralized finance (DeFi), gaming, tokenized assets, infrastructure, and Web3. But not all cryptocurrencies hold equal value—or equal risk.
This guide breaks down the major cryptocurrencies Americans are investing in today, how they differ, which ones dominate the market, and how to approach them with a smart, risk-aware strategy.
Let’s take this step by step—simple, clear, and beginner-friendly.

- Infrastructure tokens (Chainlink, Polygon)
- Exchange tokens (BNB, CRO)
