There are 2 walls(1 buy 1 sell) around 16btc each and some orders in between:the guy is probably just trying to buy some doges cheap by "locking" the price and forcing people to think it is better to sell but in any way he benefits-buy low or sell higher is same fr him so let's just not panic, he will pull the walls at some point, it is just manipulation
it is not 'one guy' - it is the sum of all who bid at that price..
stop thinking it is 'one guy' doing all this - it can be thousands of people bidding on the same value..
I said "probably" as in "I am not sure" if that wasn't clear. I think in this case most of the wall belongs to 1 person and it really looks like someone is just locking the price in by surrounding the price range with walls, I am not 100% sure, again, but it really looks like that. In any way, we will see some movement soon(when the wall(s) go down in any direction)
