Who has experienced the "Oil Treasure Incident" back then?

U.S. crude oil futures, when they dropped to one cent, someone bought ten thousand yuan.
Thinking: at worst, I’ll lose ten thousand, just for a little fun, a small pleasure.
Who knew, after half an hour,
Crude oil futures plummeted, owing forty million.
Many people don’t understand, I’ll ask to clarify:
At that time, the price was one cent,
One ten thousand yuan could buy one million barrels.
Later, the price dropped to -40.
At this point, there are two options:
1. Wait a few days for the oil delivery, rent a ship to pull 1 million barrels of oil.
2. Sell the 1 million barrels contract,
but because the price is -40,
you need to pay others 40 million to sell the contract. #原油 $CL
