Nonsense. Don't you people get tired of trying to scam gamblers in this manner? This silly scam won't work since I have observed similar threads like this one advertising crash predictions come and go in recent times.
Even if you legitimately found an exploit in Roobet, taking advantage of it is illegal and helping others take advantage of it is illegal too. Don't fall for this crap people.
This is the first time I have heard of a scam like this and from the looks of it, it has a similar scam format as the ones that provides those trade signal scams. Also, if there really is a legitimate exploit, I don't think that the person or group that has discovered that exploit is just going to show it to the world, I mean you just discovered an exploit that makes a lot of money, why would you want to share it to other people unless it doesn't work.
