Crypto gets easier to read when the nouns stop moving. Start with the machinery, then build your own questions.
01 / The map
A blockchain is a shared record kept by many computers. Blocks bundle transactions; consensus is the process that lets the network agree on the next page.
- Wallet = keys, not a bank account
- Address = where assets can be sent
- Block = a batch in the public record
02 / The motion
Liquidity is how easily an asset can trade without moving its price too much. Volume, depth, spreads, and slippage tell different parts of that story.
- Volume measures activity
- Spread measures the bid/ask gap
- Slippage is the cost of moving through depth
03 / The weather
Volatility is not a villain; it is a condition. It describes how sharply prices move, which means a calm chart can become a rough crossing without much warning.
- Size for uncertainty
- Separate thesis from timeline
- Keep an exit thought on paper
