Cryptocurrency is a digital asset class built on blockchain technology. Bitcoin, launched in 2009, is the largest by market cap. Ethereum, the second largest, supports smart contracts and decentralized applications. Crypto is highly volatile, uninsured, and subject to significant regulatory risk — but it has also produced extraordinary returns for long-term holders who survived its major downturns.

How to Invest in Crypto Safely

Step 1: Choose a regulated exchange. In the US, use Coinbase, Kraken, or Gemini — all are registered with FinCEN and comply with US regulations. Avoid offshore exchanges with unclear regulatory status.

Step 2: Enable two-factor authentication (2FA). Use an authenticator app (not SMS). Exchange hacks and SIM-swap attacks are real threats.

Step 3: Consider hardware wallet storage for significant holdings. For amounts you plan to hold long-term, a hardware wallet (Ledger, Trezor) keeps your private keys off the internet.

Step 4: Keep records for taxes. Every trade, sale, or exchange is a taxable event. Export transaction history from your exchange throughout the year.
