With the last update of Minerlotto in June/July last year, Kublai coin also went into hibernation. Kublai coin what's the link token of the minerlotto platform, being used as the in-game currency to participate in the lottery game of the platform.
The basis of existence of Kublai coin was largely integrated into Minerlotto and with it's disappearance, Kublai coin has also gone into an inactive state. This is one reason why crypto projects that are largely based on a centralised figure tend to fail the most.
With Minerlotto application off the play Store and Kublai coin websites with an unreachable server, it is safe to say that this project has been discontinued and completely abandoned.
