I don't know much about those sponsored people but I think I have seen some social media guys to win huge jackpots and you may be right about those.
Do you mean that the people who bet big on bc.game's house edge games are people sponsored by the casino?
At first I never thought about it like that, but after reading your post maybe it could happen. Moreover, seeing the game crash, quite a lot of users bet more than $1000 on the game crash. that's so crazy to me, do you think it's also sponsored by the casino?
I don't they are sponsored in anyway because you would be surprised to what and how much people really stake on gambling especially the crash games, well I don't know about the certainty but I just think it's real account that do play these games and I think bc.game is big enough to house these type of gamblers as their customers and I have others stake like and huge winnings too but the difference is that the I.D to the coupon are provided for people to get full details on the staked games but that's for soccer and other sportbets.
