The brainmining looks like only for very smart, intelligent people.
So its not justified to say its a fairer model than other mining, coz its still only possible for a small group.
How can we ordinary Joe get the coins from brainmining???
If you look at the last test it is really easy for everyone, just have to make a sum. Anyway, soon all will go up again (we are setting up the new host) and with differents task at different level of difficulty there will be chance for everyone.
better everyone who solve the question share the award, instead of only one get it
Do you mean like a mining pool? Like a dedicate page where people decide to make a pool and share their reward?
