This is pure speculation but there has definitely been a change in the rental markets over the past few days. Usually I list a few up from the bottom and wait for price to get to me. It doesn't always work but it usually does.
Right now I have cards that are usually very active rentals that haven't been rented out in several days so I've been hitting the very bottom bid if I feel like there's still room withut damaging price and every time I find myself undercut within a couple minutes. Usually with a price that has 3 digits after the decimal.
Then price will stay just below you and pretty much won't change until I go back in to retry to caputre the bottom and then the floor gets undercut again within a couple minutes.
It just feels like bots are scanning the floor and making sure they have the lowest prices no matter what.
Does anyone know of this happening? Are bots now running the markets and making sure whales always have the best prices?
