How to get zk coin?

So, I'm curious to know, how exactly does one acquire ZK coin? Is there a specific exchange I should be using? Or is there a more direct way to purchase it? I've heard that zk coin is becoming increasingly popular in the cryptocurrency world, so I'm eager to learn more about the process of acquiring it. Could you walk me through the steps, perhaps highlighting any potential challenges or considerations I should keep in mind along the way?
