I don't understand what do you mean by "trade". As far as I know, bc.game is a gambling site and you playing a crash game based on your screenshot and screen recording. You show us that the image has a different color between the website and the app, but I just a past game right? you just need to check the history on their site yourself, I don't defend bc.game but I just can't trust your word either. The last 3k games can be viewed on their website here
the detail of their crash game can be viewed here
