The representative of bc.game came online today and he posted in the scam accusations topic that he will share the findings with mumu in a personal message when they finalized the investigation. While this case is taking a while, when the claim is legit, they will pay it out. They have been in business since multiple years and all the cases against them have been resolved with success.
The way you wrote the representative of bc.game came online, and he posted in the scam accusation topic, seems like they posted today. But they were online, but they did not post any updates there. The last update they posted was on 27th July and they were asking the accuser (mamu68) to check PM and respond to them. I appreciate their approach.
But the accuser kept posting negativity during the investigation, which I don't think is necessary. The simple ting he can do is cooperate with Bc game and wait for the final result. After that, if he believes he has something to share, he could do that.
