Before you start
What this module changes in your trading process.
You can explain blockchain settlement, BTC, ETH, tokens, wallets, and the difference between owning a coin and trading price exposure.
Lesson 1
Blockchain is a shared settlement ledger
Understand blockchain as a network that records ownership without relying on one central database.
A blockchain is a distributed ledger. Instead of one company owning the database, many network participants verify and store the history of transactions.
Blocks contain batches of transactions. Each new block extends the chain and makes the previous history harder to rewrite. This is why crypto people talk about settlement, confirmations, validators, miners, and consensus.
The practical point for traders is simple: crypto trades 24/7, settlement can be public, and ownership can move directly between wallets. This creates different risks from bank transfers or broker balances.
Example
When someone sends ETH from one wallet to another, the transaction is broadcast, validated, included in a block, and then visible on a block explorer.
Key points
- A blockchain records transaction history across a network.
- Consensus decides which transactions become valid history.
- Public chains let anyone verify activity, but addresses are pseudonymous.
- Settlement finality does not mean price stability.
Practice checkpoint
Open a public block explorer and look at one BTC or Ethereum transaction. Write the transaction hash, sender, receiver, fee, and confirmation status.
Before continuing
- OKI know why crypto transactions are visible on-chain.
- OKI know confirmations are not the same as profit.
- OKI can separate settlement technology from market speculation.
Lesson 2
Bitcoin, Ethereum, and why assets are not all the same
Separate monetary assets, smart contract networks, stablecoins, and application tokens.
Bitcoin is usually treated as digital scarcity and a monetary network. Ethereum is a programmable network where smart contracts can run applications, tokens, stablecoins, and decentralized finance.
A coin normally belongs to its own network. A token is issued on top of a network. This distinction matters because the same ticker, bridge, or wrapped asset can behave differently across chains.
Beginners often call everything 'coin'. Crypto-native thinking starts by asking: what network is this on, what is the asset used for, who controls issuance, and what risk does the holder carry?
Example
USDC on Ethereum, USDC on Solana, and bridged USDC-like tokens can look similar to beginners, but the chain, issuer path, and bridge risk can differ.
Key points
- BTC and ETH have different roles and risk drivers.
- Coins and tokens are not the same thing.
- Stablecoins are designed for price stability but still carry issuer, reserve, chain, and smart-contract risk.
- Wrapped assets and bridged assets add extra trust assumptions.
Practice checkpoint
Pick five crypto assets. Label each one as coin, token, stablecoin, governance token, or wrapped/bridged asset.
Before continuing
- OKI know the asset's network.
- OKI know whether it is a coin or token.
- OKI know the main reason the asset exists.
Lesson 3
Owning crypto versus trading crypto exposure
Understand the difference between exchange balances, self-custody, spot, and derivatives exposure.
Buying spot crypto on an exchange gives price exposure and an exchange account balance. Withdrawing to self-custody gives direct control of an on-chain asset, but it also gives you direct responsibility.
Trading derivatives such as perpetual futures gives price exposure without necessarily owning the underlying asset. That can be useful for active traders, but leverage, funding, liquidation, and exchange risk become central.
The question is not which one is always best. The question is what you are trying to do: hold, transfer, use DeFi, hedge, trade short-term, or learn market structure.
Example
A beginner who wants to learn wallet usage should use tiny amounts on-chain first. A trader using perps must understand liquidation before thinking about profit.
Key points
- Exchange balance is not the same as self-custody.
- Spot ownership and derivatives exposure have different risks.
- Self-custody increases control and responsibility.
- Leverage can turn normal volatility into liquidation risk.
Practice checkpoint
Write three goals: hold, trade, use on-chain. For each goal, list the account type, custody model, and main risk.
Before continuing
- OKI know whether I own the asset or only trade exposure.
- OKI know who controls the private keys.
- OKI know whether leverage is involved.
Fieldwork
Turn the module into something you can use this week.
Create a one-page crypto map: BTC, Ethereum, stablecoins, tokens, exchanges, wallets, DeFi apps, and derivatives. Draw how money moves between them.
