This may be accomplished by using a cryptocurrency exchange such as Coinbase or online trading platforms such as Gemini, Kraken, or eToro. You establish an account with your preferred provider after verifying your address and identity, and then link it to your bank account to purchase currency. Fees vary depending on the amount you want to deposit, (eventually) withdraw, and the transactions you want to conduct. Payment methods include debit/credit cards, PayPal, and wire transfers. New investors may demand more customer help than seasoned traders.

1. Choose a Platform: Select a cryptocurrency exchange (e.g., Coinbase, Binance, Kraken) or a peer-to-peer (P2P) platform.

2. Create an Account: Sign up, complete identity verification (KYC), and secure your account with 2fa.

3. Deposit Funds: Add money via bank transfer, credit/debit card, or other payment methods.

4. Buy Ethereum: Navigate to the trading section, enter the amount of ETH you want, and execute the purchase at the current market price or a set limit price.

5. Store Ethereum Securely: Withdraw ETH to a private wallet (e.g., MetaMask, Ledger) for safety, or keep it on the exchange if trading actively.

For beginners, exchanges like Coinbase offer a simple buy option, while advanced traders may use trading pairs (e.g., ETH/USDT) on platforms like Binance.
