The Industrial Giant Reborn

Some people think that the futures income in the previous chapter is wrong.

In fact, I have never actually played it. According to the information I checked, shorting is to buy stocks (foreign exchange, etc.) and then sell them first, and then buy them back after the target asset depreciates, earning the difference.

To do long is to borrow funds to buy assets first, and then sell them for profit after the assets appreciate. The higher the leverage, the higher the profit.

Taking the protagonist as an example, to do more is to borrow 5 billion US dollars from multiple investment banks with 1 billion US dollars as collateral, and then purchase virtual gold. Then don't you have to pay another 5 billion to the investment bank?

Assuming that gold falls in the future, is it not the same as borrowing gold and selling it, and then buying it back to the borrower after the price of gold drops?

Without this borrowing process, how is this futures transaction completed? Sincerely ask, my understanding of futures has always been like this

If not how it works, how does it work? How to directly own the rights and interests of 5 billion US dollars in gold?
