This didn't happened just one place neither, it happened all around crypto gambling world as well. Now think of people who can't comprehend that ever bet is individual and you have a chance to not only lose 10 in a row at %50 win chance, but you can lose even 20 or 30 as well, to suddenly realize that when you pay small fee, you are not getting your money any time soon. They will blame the website for not sending it quick enough even though they are the ones who picked low fee.
Those people are crazy looking to be blame for the action they made maybe this people are not fit to gamble since they cannot accept the consequences on the actions they made or the certain scenarios that's not favor unto them and if we see this guy's posting a blame on a site then better to correct them so that they will learn some lesson about how those things occur and to prove that they are wrong if they spit a bad word on the casino.
