For me, it's a hope of personal salvation
So are you saying your only helping others because you see it as benefitting yourself? Interesting reasoning.
As far as guns and gold go....I can't say that interests me at all...but why someone would share this information? that is another issue...obviously they arent sharing it for selfish purposes, otherwise they wouldn't be the ones to benefit would they? You already pointed that out yourself...it would benefit them to tell no one and stock pile. So they must be sharing this information for unselfish reasons.
It is probably a different answer depending on who is sharing the infomation with you....I am guessing that sinis shares the information because he/she wants to help others...however, if it was a gun manufacturer sharing this information...you could say it was about profit...really we need to find out who the source is before we can make any assumption.
Sorry for the long winded reply...but my point really is...why question the sharer of the information...question the source and their motives. If you don't know who the source is, how can you properly question their reasonings.
