https://www.tekedia.com/ethereum-investing-2025-wallets-fees-taxes/ . Walks through everything practically: how to buy ETH properly (secure signup, KYC, payment options with fee awareness), wallet recommendations (convenient apps vs cold storage hardware for safety), managing fees (gas volatility + cheap Layer-2 alternatives), and taxes explained simply with a clear table of events — non-taxable buys/holds, taxable disposals/swaps/staking income, short vs long-term rates, plus tips on records and software. Stresses DCA, starting small, diversification, and realistic expectations. Clean, no-hype format that actually answers the questions most newbies have. Gave it a quick scan and it cleared up a bunch for me — worth the click.
