These are the tiny buys that support the bid/ask that I've discussed on other threads. These always occur during every sell-off. They usually transact much higher than the sells and the bid/ask somehow pops back up to the level of these tiny sells in spite of 100s of coins being dumped much lower. It's bizarre. If these are causing the lag, then they do it to stem panic selling (and not the other way around like everyone's thinking).
