How can I buy IoTeX?

Excuse me, I'm quite new to the world of cryptocurrency and I've been hearing a lot about IoTeX lately. Could you please explain to me how exactly one goes about buying IoTeX tokens? I'm particularly interested in the process, any prerequisites I need to fulfill, and if there are any recommended platforms or exchanges where I can safely make my purchase. Additionally, I'd appreciate any advice or considerations I should keep in mind before diving into this investment. Thank you for your time and assistance.
