/**

The first project merge by DogeKingCHN with a cooperation of Pig_Finance will be OkikuKento.

Official launch date July 20.

Don't miss out on these opportunity to be part of this epic journey!  

Measures are being put in place to rekt early snipers & that the community can safely buy after.

To avoid being blocked, only buy after the CA has been officially published.
