How do you buy Helium?

I'm curious to know, how does one actually go about purchasing Helium, the cryptocurrency? Are there specific exchanges or platforms that specialize in it? Is there a step-by-step process I should follow to ensure a smooth transaction? Are there any safety precautions I should be aware of to protect my investment? And, perhaps most importantly, how does the pricing and trading of Helium work compared to other cryptocurrencies in the market?
