I agree with you: cashing out is not the only option and re-investing is even better because it has a long-term positive effect ont the BOINC/GRC symbiosis. When looking at user motivation it is far more complex, since it is more of a spectrum than distinct categories.

However, throughout the series I'll probably focus more on non-/semi-altruistic miners because they are more likely to jump ship. The idea of this series is to provide solutions that create long-term incentive for those people in particular.

But even if we won't be very successful with these attempts, it will certainly benefit everyone who decides to stay for whatever reasons. Thus, I'm trying to include ideas that have a long-term positive effect on BOINC/GRC.

If I'm not mistaken you are planning to have your own projects become part of the BOINC/GRC symbiosis. It would be really interesting to hear your opinion on [002] if you have the time for some in-depth discussions during the next few weeks :)
