RegardsI have decided to add donate@home because of the science it indirectly supports.
I'm still not happy with the project, to me it sounds insane to burn electricity to generate a currency which is worth less than the cost of the electricity and the hardware needed to run the app. But since the project doesn't have to cover those costs, it's a win for them. All in all it doesn't seem very efficient and it takes crunching power away from real science. Maybe you should reconsider if you want to run this project instead of donating a few $$ to them.
I can say upfront that any project which produces bitcoins with no other purpose than to reap the benefits of it (e.g. money not going back to BOINC science) will not be added to BOINCstats, no matter how hard you people nag about it. Let's call that a protection of the future of BOINC. I sincerely hope other stats sites will have the same conscience.
Edit: Challenges can't be issued on bitcoin projects.
