How to buy MNGo?

Could you please elaborate on the steps involved in purchasing MNGo, a cryptocurrency that's gaining popularity in the market? I'm new to this and would appreciate a simple and concise explanation. I've heard that it's important to set up a secure digital wallet first, but I'm not sure how to proceed from there. Would you recommend using a centralized exchange or a decentralized one? Are there any specific fees or taxes I should be aware of? Additionally, what factors should I consider before making the purchase to ensure the safety and security of my investment? Your guidance would be greatly appreciated.
