why are like all values so unstable

Everything is changing so fast its hard to feel like a trade you did paid off. Naughty nice was rising and then it drops and then It rises again and now its dropping... It is irritating on how the values are adjusting so fast. Scythe dropped 50k in one week, Spiked knuckles is dropping but its going to end up bouncing back as its the most damage dealing weapon after all. And all these other high tiers are dropping too, and all the greedy people requesting a 25k+ tv OP
