Why is it hard to buy XRP?

I've been trying to get into the crypto market and specifically, I'm interested in XRP. But, I'm finding it quite challenging to purchase. Could you please explain why it's so difficult to buy XRP? I've looked at several exchanges and they either don't support XRP or the process seems overly complicated. Is there a particular reason for this? Is it due to regulatory issues, limited availability, or something else? I'm really keen on adding XRP to my portfolio but this hurdle is making it difficult. Could you shed some light on this matter?
