Which crypto exchange has the cheapest fees?

I'm always looking for ways to maximize my investments, so I'm curious about which crypto exchange offers the most competitive fees. With so many options out there, it's difficult to determine which platform truly provides the best value for money. Could you elaborate on which crypto exchange typically has the cheapest fees? Are there any hidden costs or additional fees that I should be aware of? Furthermore, are these fees static or do they fluctuate based on market conditions? Your insights would be greatly appreciated as I strive to make informed decisions in the crypto market.
