Yesterday, I just discovered a new Blockchain. It's @miq-test. There is a daily IQ tests which you are going to answer. 10 questions, and whoever gets the highest score will win, and receive the prize. At the moment, the prize is not that huge considering the app is at its early stage. But as soon as it receives support, it will surely kick off.
As I just joined yesterday, I am glad that I won the IQ test of the day!
It's very easy! So come and join, and test your IQ!
