That's what happens when basically a single (margin) bot is trading the price down all day long on very very low volume. Whenever someone sells into an order the bot tries to makes sure that the price does not go back up again. Often enough it works and it drags the next seller down just a bit more. Buyers sit aside and gobble up some cheap coins every now and then as long as other people are giving coins away at that price (it is absolutely beyond me why someone would sell at these levels, but i don't chase shitcoin pumps and i do not need quick money).
