Where can I purchase ICP?

Could you kindly guide me as to where I might be able to acquire ICP? I've been hearing a lot about it recently and am interested in adding it to my portfolio. I've checked a few exchanges but haven't found it listed. Do you have any recommendations for reliable platforms that offer ICP trading? It would be greatly appreciated if you could point me in the right direction. Additionally, are there any specific considerations or steps I should take when purchasing ICP? Thank you for your assistance in this matter.
