More importantly, this is not a deposit but a bond

It is equivalent to Evergrande selling you a bond with a face value of 100 at a price of 100u, with a daily interest rate of 0.5%.

After Evergrande gets the money, 80%+ will be used for real estate speculation, and 10% will remain in the account. If you want to withdraw it, you can use this money to redeem it.

Evergrande borrowed money from 100 people and got 10,000U, 1,000U in cash on the books and a 9,000U house.

Whether Evergrande can pay you back depends on two factors:

1) If Evergrande can continue to borrow money, there will always be cash in its books to return to you.

2) If Evergrande cannot borrow money, it will need to use the house to pay off the debt after running out of cash on the books. This situation may cause the capital chain to break and housing prices to plummet.

As for whether you should lend money to Evergrande, and whether it is more profitable to lend money to Evergrande or to buy a house in Evergrande, it all depends on your opinion.
