All the things you could wish for and that is what you wish for lol So in short you would prefer a hacker to dump all over the market over someone holding through the rises? Me too, but I find it hard to believe he is a newb whale and you really shouldn't call anyone out for being newbie when you have no idea.
I believe he's indeed trying to hold the price down, getting more coins, or maybe trying to cut competition for other coins. There's no way you have that kind of money and put a buy wall like that even though there's not enough liquidity.
As long as there are no people with this kind of money ready to smash him we will stay at this price.
