Looking at both documents, I noticed a large amount of copied/pasted text. How did you come to the conclusion that it was only 8 pages? Even the table of contents is almost identical. Did you even look at the original document and compare it to your own?
In any case, plagiarism in itself, regardless of quantity, is a pretty big omission and very bad for any project. Whitepaper is the backbone of the project and should not be taken lightly.
By the way, a great relationship with potential customers. I admire your communication skills.
We will see more of this situation because the DeFi hype is not over. So most of them are in a hurry to deploy their project to the public to get their share of the DeFi hype. With this, they overlooked some of the vital component of their project, which in this case is their very own whitepaper. As they hired someone to do that, it is aggravating that they didn't even check the content of their own whitepaper, which is basically the heart of their project. I hope people are not so gullible from this mistake and just forget what has been done. Because later on, you don't know what kind of problem you will gonna encounter because of this rush preparation.
