What are the main steps for a beginner to buy and store Ethereum (ETH) safely in 2025?

According to Tekedia’s 2025 guide, a beginner should first sign up at a trusted exchange (and enable two‑factor authentication), complete identity verification, then choose Ethereum (ETH) and select a payment method depending on convenience and fees (e.g. bank transfer, card, etc.) https://www.tekedia.com/ethereum-investing-2025-wallets-fees-taxes/. After purchase you must enter your own wallet address — ideally on the Ethereum Mainnet — to receive ETH. For security, new users are advised to store ETH in a secure wallet, starting with small test transfers before committing larger amounts, and consider hardware or cold wallets for long‑term storage.
