Where to buy quantum currency?

I'm curious, where exactly can one purchase quantum currency? Is there a specific exchange or platform that specializes in trading this type of cryptocurrency? And, what are the steps involved in the purchasing process? Is it similar to buying other popular cryptocurrencies like Bitcoin or Ethereum, or does it require a unique approach? I'm interested in diversifying my portfolio and quantum currency seems intriguing, but I'm unsure where to start. Can you guide me through the process of acquiring it?
