When you do mentioned that he do only need $100 deposit for you to get or win constantly in the site then you would surely think of, on why the hell he's been sharing of this
holy grail and make himself gain those amount?
It doesnt need for him to hide even he's the moderator since he can create new account and made up a deposit for himself and abuse if such bug do really exist in the first place.
Aside from it being a scam, assuming that the offer is legit and the event happens that you won the said jackpot price and by some chance, players noticed the abnormal thing about that winnings and file a complaint, it will give us a problem if the complaint is justified and we will be charged as an accomplice to the crime. Giving in will only lead us to the losing end whether the guy's offer is real or not.
It isnt really that much of a bothering thing since these kind of offers doesnt exist in the first place if there are people who do have access on altering sites results.
In case if this one is legit then once you get caught then be sure to face up charges but i would say that its hard to trace out someone specially if we do deal up with things online
how much more if we do deal up with crypto.
In first glance this is clearly just a scam attempt.
