Years ago, in pennystocks, I came across the same situation.. I would find "computer sells", thats what I called them back then, on illiquid stocks.. I would gobble them up as soon as the computer selling algo was finished and it worked brilliantly.. My understanding is that at times a broker will need to offload a huge amount of some stock and so as not to drop the market, he will have a computer sell in small equal amounts every minute or two, hitting the bid.. I loved finding these trades, because it was easy money for me. It clearly identified a drop being created by one person, and that never stays down.. One person cannot decide market price... Anyway, I'm not sure if that is what you have stumbled on in crypto, I would have to see it for myself, and it would have to be on a low volume coin, where one player could actual affect the price..
