iQCash: Solve an iQ puzzle => earn 1 iQCash. (Mining with POHW - Proof of HUMAN work)

With 4 weeks left till iQCash puzzles go live, we're running a contest to see who can solve the puzzle on the back of the iQCash token.

The challenge is to identify the missing value in the center square.

The prize:

0.02 BTC if solved in the second week (i.e. Nov. 9th - Nov. 16th)
0.04 BTC if solved in the third week (i.e. Nov. 17th - Nov. 23rd)
