Crypto traders often use the word futures for very different products. A perpetual swap on a crypto exchange has no fixed expiry and uses funding payments to keep it near spot. CME cryptocurrency futures are regulated, cash-settled contracts with defined specifications, expiries and margin rules. CME’s public pages describe Micro Bitcoin futures sized at 0.1 bitcoin and Micro Ether futures sized at 0.1 ether, designed for more precise exposure than larger contracts.
The distinction matters when trading basis. Basis is the spread between futures and spot, or between two related futures curves. A positive basis can reflect financing cost, demand for leverage, hedging pressure or expectations about future spot prices. It is not free yield; it can narrow, invert or widen against a position.
CME’s cryptocurrency futures FAQ also describes multi-asset futures, including an Ether-to-Bitcoin ratio contract where buying the ratio expresses a view that ether will outperform bitcoin and selling expresses the opposite. That is a different risk profile from simply buying ETH or shorting BTC on a perpetual venue.
A practical checklist starts with contract unit, tick value, expiry, margin, settlement method and trading hours. Then compare the hedge instrument with the asset being hedged. A spot exchange position hedged with CME futures may still carry exchange basis, timing, liquidity and currency-conversion differences.
For smaller accounts, micro contracts can reduce notional size, but they do not remove leverage risk. A smaller contract is easier to size; it is not easier to predict. Traders should still predefine maximum loss, roll dates and what happens if spot and futures diverge during a liquidity shock.

Risk notice: Futures and basis trades can lose money quickly. Margin calls, expiry rolls, liquidity gaps and imperfect hedges can turn a seemingly neutral trade into directional exposure.
