I don't think the goal of the whitepaper is only to prepare an ICO nor any kind of fundraising, IMO it can be used to give a better understanding of the whole model of your business/project for anyone who wants to involved in it. Although you don't even gonna publish an ICO I think it's still important to have a whitepaper since most people don't easily put their money into an unknown business/project.
For me it's strange a project that did not have a whitepaper, because in whitepaper everything is explain deitaled. but he seems didn't care, even he already make a new step in this forum by hold some campaign on this forum.
https://bitcointalk.org/index.php?topic=5290918.0 Every individual has their own opinions on it and yes you can call it a strange one. But for me, it's something like the project doesn't have a strong foundation, just offering nonsense.
Since BTF tokens already tradeable on some various exchanges I guess most hunters would ignoring the legitimacy of the project and grab it as much as they can.
You both aware that your view about whitepaper is not contradicting each other, right? One said this project still need WP because it give a better understanding of project, the other said this project is strange because they didn't have WP that explain details (about the project).
And yes, WP is not just for ICO, it's not a mere offering letter that can be removed just because someone didn't ask for funds, it was an official in-depth documents explaining about the current issue, your plan, and everything related to your project
