Do futures have a time limit?
Excuse me, could you please clarify something for me? I've been hearing a lot about futures trading in the cryptocurrency market, and I'm curious about their nature. Do futures have a time limit? I mean, are they valid for a certain period of time, or can they be held indefinitely? It would be great if you could elaborate on this aspect. I'm particularly interested in understanding how this time limit, if any, might affect trading strategies and risk management. Thank you for your time and expertise in this matter.
