Nowhere is your hack worth $1200 or $600 a month. Add the source code and 10 copies of the game to it cause of the bans you'll receive, then you can expect that amount of money. Also it's really shady that there are no trials and you only accept bitcoin. Not to forget that vouches from any other sites don't mean anything on here.
And about the proof (video) you provided, your hack does indeed look obvious. Everyone who has played a fair amount of time with McCree knows that you don't flick vertically but horizontally.
