OP was right on his first prediction but he was right like on the last seconds of it, now he said 5th of September and we are still far away from it, maybe right on the nose at the 5th of September it will fall again, we can't know that, we have to wait and see how it does. Dude even said maybe price will go up in Sunday before it falls and it did exactly that (maybe went over a bit to Monday) so I think he is still doing fine.
In order for me to say that this dude has been proven wrong the price has to be over 9k by the 6th of September, if the fall doesn't happen than I will say he was wrong. There are plenty of people who got it right just once, we need people who get it right all the time (or mostly) and I hope OP is that person but if not well I have not put my money in anywhere he suggested so I will be fine.
