I have been watching the charts consistently throughout the day for a few days now, observing the ask walls. Its fairly obvious that someone is keeping the price low and buying cheap coins through placing bids lower than their ask walls. They are hoarding cheap coins by getting people to sell into their bids and buying coins lower than their ask walls. They are pretty blatant about it, even placing the walls at $1 intervals.

If they decide they have reached their desired amount of coins and then lift their ask walls, bitcoin will rise, which is what they want after buying lots of cheap bitcoins.

Whomever is doing this is pretty clever as they are also doing a couple of other things to stunt the price. If you think the price is going to drop, it will not. The ask walls are keeping the price low.

You should zoom out even more, make it look like a smooth line.
