Is there also a saying that neutral grid can be liquidated?

Answer: Yes, I have personally experienced it.

I had nothing to do in the afternoon, so I spent half a day playing around with grid contracts and spot trading. It was quite fun.

I thought the grid was very stable and would not go bankrupt.

I opened a neutral contract with 6 Doge 11 times

How many grids do you open? How many times?

Oh, I was naive.

The grid is not called a margin call, but a forced liquidation of the grid due to insufficient margin allocation.
