Understand crypto without starting with a trade. CryptoTechToday explains wallet responsibility, transaction fees and digital-asset risks in plain English, with practical exercises for beginners and Australian-dollar examples where useful.
Start here: a five-guide learning path
No account, deposit or wallet connection is needed to read these guides or complete their exercises. Follow them in order, or choose the question you need answered.
- Who controls the assets? Read the wallet and custody guide. Use its five-question worksheet and lost-phone example to separate an exchange login from a self-custody backup.
- What am I being asked to sign? Use the crypto security checklist. Work through a fictional wallet-repair scam and learn why disconnecting an app is not the same as removing an on-chain permission.
- What does a transaction cost? Study Ethereum and gas fees. Reproduce the ETH and AUD calculations, then distinguish the gas used from the price paid for each unit.
- How do I compare services? Read the exchange comparison guide. Its fictional fee exercise shows why the smallest advertised trading charge may not mean the lowest total cost.
- Stable in which currency? Try the stablecoin AUD-value exercise. Separate a token’s dollar peg from the exchange-rate exposure of an Australian reader.
Check what you have learned
After those five guides, try explaining these distinctions without looking at the answers: an account password versus a recovery phrase; a trade quote versus an executed transaction; a network fee versus a platform charge; and a US-dollar target versus an Australian-dollar value. If a distinction is unclear, revisit the linked exercise before considering any real transaction.
