Perpetual futures contracts are a type of derivative that allows traders to speculate on the price of digital assets without an expiration date. The Futures Open Interest Crypto Margin Perpetual metric measures the total amount of funds (in USD value) allocated in open perpetual futures contracts that are collateralized with digital assets instead of cash. This metric is useful for assessing the level of market participation and the amount of capital at risk in crypto-margined perpetual futures. For example, you might ask, "What is the total crypto-margined open interest for Bitcoin perpetual futures across all exchanges?"
