I've added information on AGRO to my book Altcoin Investigation 2019-08.  You can download it for free here : http://altcoininvestigation.com?utm_source=bitcointalk&utm_medium=AGRO.  after you click on the download link you will see a slider - slide it all the way to the left to download it for free.  If you see anything written about AGRO which is incorrect, please let me know - thanks
