How to buy mnt on mantle network?

Could you please elaborate on the process of purchasing MNT tokens on the Mantle Network? I'm particularly interested in understanding the steps involved, including any prerequisite steps I might need to take, the platforms or exchanges I should use, and any fees or commissions associated with the purchase. Additionally, it would be helpful to know if there are any security measures I should take to ensure the safety of my transaction. Thank you for your assistance in guiding me through this process.
