hi there.  I've added DigitalBits (XDB) to my book "Altcoin Investigation 2019-09."  I wonder if someone could verify that I got the information about the coin correct (preferably from a member of the team) ? I went through the whitepaper and extracted business problems which could be solved by using the token, and it would be nice for me to know that the info I got from the whitepaper was still relevant.  The book costs about 10 dollars, but for the purposes of textual review you can pay for the book, download it, review the XDB portion, and then get back to me with any corrections, and then get your money refunded (you have 45 days after purchase to refund the book).  To access the book, go to my voting page here : http://altcoininvestigation.com?utm_source=bitcointalk&utm_medium=XDB (that's where people can vote for which coins to add next to the book), make sure the 2019-09 year/date combination is set and then click the download link at the top. The book is continually being updated and people who have bought the book can redownload it as many times as they like - i.e. all updates are free once you pay for the book, and I've been updating the book every few days.  If you get a refund then of course you won't get updates.  When explaining why you are asking for a refund please let the publishing company (leanpub, in this case) know that you downloaded the book to verify the XDB section, per an agreement made with the author, and that the author is expecting the refund to be made. Copying a link to this bitcointalk post might be the easiest way to do that as the publisher can then verify with me that I in fact posted the message on the forum.  thanks
