/why-pay-puh/ (noun):
the wholly un-ironic bastardization of traditional academic white papers, released in due course of shilling one's non-functional and conceptually-useless cryptocurrency (shitcoin) and an integral component of the market-priming process for its eventual dumping upon the clueless masses.
Often nothing more than a 5-page PDF dedicated to shoddy marketing points as opposed to any substantive technical discourse, the document is intended to persuade potential "investors" (suckers) as to "why" they should "pay" their hard-earned money for a more-often-than-not-still-imaginary "asset" with no empirical or practical value, real-world use cases, consumer adoption benefits, or general conceptual graspability among the greater populace.
