I have checked the website and was also watched the reviews and see some non-popular in this forum are getting the top ratings. I can not understand it is actually given after testing the website or paid review or you arranged the list according to given Bonus  %? For example betflip. Just see a thread against betflip that they are cheating with user by giving deposit bonus despite the user does not want it. Here is the thread : https://bitcointalk.org/index.php?topic=5356229.0
