That is one of the problems with the current reward system in Gridcoin.
It takes research away from popular projects like mapping cancer markers to things less important. Although, I would argue that taking research away from SETI (searching for aliens) is a good thing, but only if it goes to something more important.
The same thing happened to me but now I have switched all my hosts back to WCG (mapping cancer markers) and stopped chasing profit.
IMO we need to look at changing the reward system so that Gridcoin does not influence what projects people crunch.
I'm not sure if that is possible though.
If not, maybe we can use the voting system to vote on a % reward allocation for each project so that the monetary incentive forces people onto the most useful projects.
