What does MTF or FTM mean?

Could you please clarify for me what the abbreviations "MTF" and "FTM" stand for in the context of cryptocurrency or finance? I've been trying to research these terms, but I'm still not entirely sure of their meanings. Could you explain the significance of these abbreviations and how they are used in the industry? Additionally, if there are any related concepts or terminologies that I should be aware of, could you also provide some insights? Thank you for your assistance in clarifying these terms for me.
