Dentacoin is not minable but pre-mined. The total DCN supply is 8 trillion DCN, but they will be unlocked gradually following a schedule:
Around 40% of the total amount of Dentacoins are reserved for EARNING (through tools and value-generating activities, contributing to the
improvement of the dental industry), 40% are reserved for BUYING (ICO and pre-sale activities, crowdfunding) and the other 20% is to be
utilized by the Dentacoin Foundation for development of tools, marketing activities, bounty programs, future projects and unpredicted expenses.
