They are business, they should not use false information to promote their service.
Without tx id/or winner testimony those made up banners are worth nothing.
If you don't want to believe the winning players here on the Roobet then nothing will force you. Don't waste your time and just focus on your own campaign. Also, how do you know that these are just false information?
Is it just because you have nothing to expect?
There are actually winning players who don't want to be informed or give their testimony, presumably for their privacy and security.
I'm pretty sure that they are fake, because not even bet id is provided, just words. They are not high on trustworthiness scale.

I've been a lurker around bitcoin talk for a while and also an avid player of Roobet a few months now, I'm down several hundred dollars there but your baseless claims are too hilarious not to comment to so I've had to dig out my ancient account, don't get me wrong from what I've seen they've still got a long road ahead from them and they are still relatively new but your claims are hysterical.
A casino doesn't need to prove the legitimacy of any bets to someone like you, and as this was a live casino game sourced by a third party, you don't seem to know how they work, typically the provider will charge a percentage on each bet or the profit the site makes overall from their services, you're trying to say that Roobet simply sits their all day placing bets on their games while racking up fees with their providers or made the win out of thin air to mislead users? I'm part of a roobet discord with some friends in the community and this was shared there
https://prnt.sc/s8v7dq - seems like it must be fake right?
no, I didn't think so. I think any casino in the right mind would want to capitalise on such a win, and you're really firing them down for that just because you seem to have a grudge against them?
You also question the capability of Roobet paying out a bet of this size, casinos like this typically are a multi-million dollar business & have a huge amount of investment behind them, they'll probably make at least $250k back in a few days, if not double that, they work with a lot of influencers which probably have brand deals consisting of tens of thousands, I couldn't see a business of this size sacrificing their integrity for that, I really can't comprehend your logic, it's beyond me.
Hey wise ass if they are so legit then why do they need to have twitch streamers place high stakes bets on blackjack/slots/monopoly etc with fake money?
Sorry but that practice is very unethical. Its really scummy especially when the target audience on twitch are teens and young adults that don't have much money. But they see their favorite streamer placing $500 blackjack bets with fake money and think they can do that to. Its a very dangerous road to go down if they ever want to be a respected online casino, which at this point I doubt will EVER happen.
Also, the twitch streamers encourage anyone in gambling jurisdictions where its illegal to play online to bypass those filters set in place by government to fake their identity and location with VPNs. Again very scummy especially since Roobet has in ther terms of service that using VPNs is specifically against the rules. But they are only there for show they are looking the other way for now.
They don't care if kids underage is gambling on their site because they do no checks. All of this is super shady.
I won't stop exposing the scum that roobet is because I've been gambling online a long time and I know a shady ass casino when I see one.
