Where can I buy Polyx?

Excuse me, I've been hearing a lot about the cryptocurrency Polyx lately and I'm quite intrigued. Could you please elaborate on where I could potentially purchase this digital asset? I've been searching online but there seems to be a plethora of options and I'm not sure which one is the most reliable. Additionally, I'm also concerned about the security and privacy aspects involved in making such a transaction. Would you be able to recommend a secure platform or exchange where I can safely buy Polyx? Your insights would be greatly appreciated.
