Can you trade futures without margin?

I'm curious, can you engage in futures trading without utilizing margin? It's a topic that often leaves investors with questions, especially those new to the world of finance and cryptocurrency. Futures trading, in essence, is a contract to buy or sell an asset at a predetermined price and date in the future. But I've heard that margin is often required as a form of collateral to ensure the trader can fulfill their obligations under the contract. So, is it possible to navigate the world of futures trading without relying on margin, or is this a crucial aspect that all traders must be aware of and utilize?
