How to earn playing MAVIA?

I'm curious about how one can earn by playing MAVIA. Can you provide a detailed explanation of the earning mechanisms within the game? Do players earn through in-game achievements, competitions, or by completing specific tasks? Are there any special rewards for reaching certain milestones or levels? Additionally, how do these earnings translate into real-world value, such as cryptocurrency or other forms of payment? I'm particularly interested in understanding the economics behind the earning process in MAVIA.
