What is this wallet doing to generate significant profits almost every minute?

Hey,

I came across this wallet on GMGN: DfMxre4cKmvogbLrPigxmibVTTQDuzjdXojWzjCXXhzj. This wallet trades a lot. Over the last 30 days, it has made +$1.3M. The transactions follow a similar pattern. It usually buys for around $420 and sells about a minute later for significant profits. How is this possible? It doesn’t seem like the wallet has insider information, but maybe I’m wrong. I’ve noticed that after each of its purchases, there’s often another transaction investing around ~$1500. Are these amounts triggering alert bots, or is there some kind of scheme behind this?

I’d be very grateful for any insights.
