How to use this hub
Crypto's vocabulary is intimidating on purpose. Most terms describe simple ideas wrapped in jargon by exchanges, developers, and marketers. Each guide here picks one term, gives the one-sentence answer first, then explains it for a curious beginner. You can read them in any order, and nothing here is financial advice.
If you are brand new, start with Bitcoin and crypto wallets. Together they cover what crypto actually is and how you hold it yourself. If you have already opened an exchange account, KYC and gas/gwei are the two terms you will hit on day one. DeFi and airdrops sit one layer deeper and assume you already control a wallet.
Every guide ends with a Sources block linking to primary documentation โ bitcoin.org, ethereum.org, the EIP-1559 spec, and FinCEN โ so you can verify the claim yourself. The hub is current to 2026 and reflects the upgrades that matter: Ethereum's 2022 move to proof-of-stake, EIP-1559's burn mechanism from Aug 2021, Bitcoin's 2024 halving, and the May 2025 Pectra upgrade.

Common questions
Where should a complete beginner start?
Start with Bitcoin and crypto wallets. Those two pages cover what crypto is and how you actually hold it. From there, read Ethereum and KYC โ they explain the rest of what you will see on any exchange or app.
What is the difference between Bitcoin and Ethereum?
Bitcoin is digital money with a fixed supply of 21 million coins, designed for peer-to-peer payments. Ethereum is a programmable blockchain that runs smart contracts โ small programs that can hold and move value. That is why DeFi, NFTs, and most stablecoins live on Ethereum, not Bitcoin.
Do I need to understand all of this before I start?
No. You need a basic grasp of wallets and KYC to use an exchange safely. You can learn DeFi, airdrops, and gas as you encounter them. The one rule that never bends: do not sign a transaction you do not understand.
Why does every crypto page mention gas fees?
Because every Ethereum and Layer 2 transaction costs gas to run. Since EIP-1559 in August 2021, the fee has two parts โ a base fee set by the network and burned, and a small tip to the validator. Bitcoin has its own version measured in sats per virtual byte.
Is crypto safe to learn about?
Reading is risk-free. Real risk starts the moment you hold real funds โ phishing sites, fake claim pages, wrong-network sends, and contract approvals you did not read can all drain a wallet. Each guide here flags the common failure modes so you can avoid them.
Do these guides cover taxes?
These guides mention tax treatment only where it is directly relevant โ for example, the IRS treats airdrops as ordinary income at fair-market value on receipt in the US. For your country and situation, talk to a tax professional. Crypto tax rules vary widely and change often.
