Iran is no longer fighting, can the crypto market go up?

Not necessarily. War only increases the probability of decline; the core issue still comes down to the crypto market itself lacking new narratives and growth. Simply put, the story has been told. If stopping the war is considered a positive signal, you can look at the Russia-Ukraine conflict—markets only dipped briefly and recovered all losses that same night.
Looking further back, during the decentralized revolution, Bitcoin was dubbed digital gold. Theoretically, the more chaotic the world, the more Bitcoin should rise. So why has it been falling steadily during this period?
The essence of finance is a game of survival of the fittest. No matter how you see it, there are reasonable arguments to justify your stance. Our main goal is still how to earn more USD. In this market environment, the best you can do is avoid losing money, make some small trades, and earn a few thousand dollars each month—covering living expenses—already beating 99% of people.
