I have the feeling that copying documents, in particular white paper, is a common practice among cryptocurrency exchanges. Even the largest exchanges such as Binance did not hesitate to copy a bit from Bitmex exchange. I understand that all exchanges are similar, not all of them are scammers, but such behavior depresses me anyway.
Unfortunately, there is a lot of plagiarism, and the links I posted are not the only resources. To create such a document, the developers stole several other people's phrases from other sites.
You can see for yourself by checking their document yourself. There is a lot of other people's material.
