FK token is the only global token of the FKEx autonomous mining pool trading platform, referred to as FK. Initially issued based on the Ethereum ERC 20 protocol, it will be transferred to the self-developed public chain in the future. The total amount of issuance is constant at 900 million, and there will never be additional issuance. The automatic execution of smart contracts is halved every 2 years. FK holders have a series of rights and interests such as participation in community governance, voting, and supervision. Every quarter, 30% of the net profit of the platform will be used to repurchase FK, and the repurchased FK will be directly destroyed until the total amount of 200 million FK tokens is destroyed. Repurchase will make FK extremely deflationary and scarcity will increase.
