However, it cannot be used to purchase DNA or exchanged for $TOWN. Conversion can only be done in increments of 10,000 Mile, with a minimum conversion amount of 10,000 Mile or more. The maximum amount of Mile that can be converted per day is 50,000 Mile. The value of Mile is fixed at 0.75 USDT per 1,000 Mile, and the circulating supply is regulated through exchanges with KEY.
