I can only imagine how absolutely shit your whitepaper will be if you only charge $80 to write it.
Likewise, I can only imagine how trash a project must be in order to think $80 is a reasonable price to pay for a critical document.
There is a reason writing agencies charge several thousand dollars for these documents.
The reason i charge this depends on customer to customer. i can also charge $1000 plus but everyone has a budget, for instance a one pager document why shouldnt i charge $80 for such a simple project?
Bro, a whitepaper and a one-pager is completely different.
You clearly mentioned that you charge $80 for a whitepaper. e.g. a multi-page document that outlines the specifics of a project, plans for the future, token allocation (if applicable), etc.
Even if it's $8/page for a 10 page document, I don't see how you could possibly produce anything substantial for $80.
That said, $80 is a fair price for a basic one-pager, but you did say $80 for a whitepaper.
