I'm still having trouble wrapping my head around the tithing concept, at least at the ELI5 level. Let me think out loud and maybe we can work it out.

In the traditional sense, tithing is a sort of 10% tax. If I make $1000 a month, my 10% tithe leaves me with $900.

In terms of Boinc, I'm pledging a certain amount of electricity/computing power, and in return I receive a small amount of GRC/Byteball/DCC/BBP/Neumanium.

In the new concept (as I understand it), I can tithe some percent (let's say 10% again) in BBP, and in return I get some amount of BBP. How much I have no idea, or how to take a guess)

This isn't my opinion, but I think the following is a valid question:

If we're really trying to promote giving, why are we getting a kickback reward for the tithing? If I get Y% reward for tithing X%, wouldn't it be more giving to donate X% + Y%? Isn't effectively our tithe reduced by the amount of our reward? You might say the same for Boinc, but there's no return of electricity--it gets used regardless (kind of like traditional tithing).

This isn't my perception, but I think it should be thought out--that to an outsider, the "giving" part of proof-of-giving, isn't a full give, there's a refund involved. Maybe that's the carrot that gets the giving started to begin with?)

It may be that we need to trick encourage people into giving? But for a coin that is charity-based and Christian-based, it might seem odd to be rewarding giving with the same currency (which brings up donating X + Y%). I would always think, "how am I benefiting directly from this giving, is this right?".

Now one could make the same argument for Boinc, but there are two key differences. Boinc is scientific research, not spiritual in nature. And two, that the payment from Boinc isn't in the same currency coming in and going out. If we are totally honest, it seems that a 10% tithe, after rewards, leaves us with more than 90% left.
