Bitcoin derivatives: understand the whole arrangement
Separate bitcoin price exposure from coin ownership, and compare collateral, reference prices, and settlement.
Price exposure is not coin ownership.
Bitcoin futures, perpetuals, and options create contractual exposures linked to bitcoin reference prices. A financially settled contract does not by itself provide a bitcoin balance in a wallet. The contract, collateral, reference methodology, and settlement process all belong in the same comparison.

Distinguish last trade, index, mark, and settlement.
Check currency, eligibility, haircuts, and transfer access.
Compare expiry, rolling, funding, and option premiums.
A comparison based only on headline leverage or opening fees misses the whole arrangement. Translate the contract quantity into notional exposure, identify its payoff currency, and write an adverse-price scenario. Cash needed for margin may not be available from an offsetting holding elsewhere.

A hypothetical 0.10 BTC linear exposure loses $100 when its quoted price falls $1,000 per bitcoin, before costs. The amount initially deposited does not change that arithmetic.
Examples are simplified and exclude fees unless stated. Actual payoff formulas, margin rules, and eligibility vary. Read risk information.
