Is trading Boom and Crash a shortcut to profits, or just another trap for beginners?

If Boom and Crash indices are actually profitable, why do so many beginners struggle to make consistent gains? Are synthetic indices genuinely designed to provide trading opportunities, or are they structured in a way that primarily benefits the brokers by exploiting new trader’s lack of experience? Would love to hear from those who have mastered them on this forum…what’s the real key to success?
