Seems like someone is trying to keep the price low. Everytime the price goes up somebody sells a very small amount to drop it back down.
Very strange! Or is there a positive reason for this?

government maybe ? just kidding, if I would sell would be like several 100's of $ with Todays inflation pfffff why would I even bother like seriously, few groceries shopping trips and profit is over (minus some electricity costs)
maybe exchange does that to keep transactions liquid, a bot, sell this then buy back.. one could trace via an explorer if one wants to bother to look
