Where can I buy XEP?

Excuse me, I'm trying to get my hands on some XEP tokens but I'm having trouble finding a reliable platform to purchase them from. Could you please point me in the right direction? I've heard about a few exchanges, but I'm not sure which one is the most secure and offers the best rates for XEP. Additionally, are there any specific steps or precautions I should take while making the purchase to ensure a smooth and secure transaction? Your insights would be greatly appreciated.
