* Token Ming is a cryptocurrency project with a total supply of 100 million tokens.
* A unique feature of Token Ming is that 4% of the token supply is reserved by the 
* development team to cover initial and future expenses. This allocation ensures 
* the project's sustainability and growth. Additionally, 2% of all sales made through 
* Token Ming are allocated to marketing efforts, enabling the project to reach a wider 
* audience and enhance its visibility. These strategic allocations support the 
* development, maintenance, and promotion of Token Ming, ensuring its long-term 
* success in the cryptocurrency space.
