can you give a remote node, can not use brainming in the application
You can go here:
http://www.diracoin.org/braincypherfor example:
each question will stay 1 minute, even it have been solved, it will still stay 1 minute for the rest people to submit their answers
in this 1 minute, if there are a total 10 people solved the question, these 10 people can share the awarding together
in this way, everyone can participate and get rewards, instead of turning into a smart guy game
If all users can gain the "same" amount of coins we fear the risk to devalue the coin. A bit of competitive it's necessary. What we can do instead, if users agree, it is to implement a timer for every task with a deadline of, for example as you said 60 seconds, and give every users a reward based on the time they needed to solve it, in order to make anyone to gain even a few coins.
I dont think everyone should get 75 coins then, but a share of the 75 coins. Maybe bump it up a little, because at the moment more than 75 coins are handed out in a minute. So if you give 300 for a minute shared by participants, that could be okay, I guess?
