Things about crypto that are commonly misunderstood

Why it matters

Bad mental models produce bad security and market decisions long before a reader reaches advanced technical material.

Market cap is a multiplication

Reported market capitalization generally multiplies a reference price by a defined circulating supply. It does not show how much money entered, how much could exit at that price or what every unit could be sold for simultaneously.

Price is usually formed at the margin. In a thin market, a small amount of trading can change the reference price and therefore revalue the entire displayed supply on paper.

Volume needs a venue and method

Reported volume can combine venues with different rules, quote assets, incentives and data quality. It may include repeated trading, market making or activity that is not new long-term demand.

Use volume to ask where activity occurred and how liquid a route may be. Do not convert a large aggregate into buying pressure without defensible trade classification and coverage.

Technical confirmation is not total safety

A network may finalize a valid transfer to the wrong address. A stablecoin can transfer correctly while its issuer or reserve later fails. A bridge token can move correctly while the locked collateral is compromised.

Likewise, proof of reserves can reveal selected assets at a point in time without revealing complete liabilities, control or activity between snapshots. It is not automatically a financial-statement audit.

Decentralized is not ownerless

Control can be distributed across validators while interfaces, oracles, custody, development, governance or liquidity remain concentrated. Open-source code can still depend on a small operational team.

Replace the adjective with questions: who can upgrade, pause, censor, recover, issue, redeem, list or move the relevant asset? The answers are more useful than the label.
