I found that with a small position, I can earn a lot,

Yesterday, I lost 30,000u with a heavy short position.

If it were still that position, memefi could at least make back the losses and earn a few tens of thousands more.

I opened with 150u, and it has rolled down. I've made a small profit of 5,000u,

The charts for today's biggest drops and gains were all controlled by A Ding.
