How to buy DFI money?

Could you please elaborate on the steps involved in purchasing DFI money? I'm particularly interested in understanding the process from start to finish, including the platforms where DFI can be acquired, the necessary account setups, and any specific considerations or precautions I should take during the transaction. Additionally, would it be possible to get an overview of the fees associated with buying DFI, as well as any potential risks or limitations that I should be aware of? Thank you for your assistance.
