On the second day of arriving in London, there was Katie's game in the morning.

With blue eyes, a height of 1.82 meters, and a sturdy and well-proportioned look, Katie did not disappoint Zhang Jing and the audience, she once again defeated her opponent and created a 17-game winning streak as a dark horse, entertaining the public while also making gamblers make a lot of money.

After the game, of course, Katie was once again surrounded by sports reporters and self-media reporters.

Zhang Jing took Ding Jiaqi by the hand and looked at the high-spirited and confident girl on the periphery and calmly answered the reporters' questions.

Until Irina in the crowd gets a chance to ask a question, seemingly unintentionally, "Miss Katie, how do you spend the prize money you earn?"

Irina is a little hairy girl, a brown-haired girl, the big place is big, the place should be small, she entered Citigroup as a refugee, Zhang Jing's classmate at the same table for a month, responsible for operating the video account and writing small advertorials.

Katie looked at Irina with the same attitude as she answered the other people's questions, and said with a bright smile on her face, "I have deposited all my money in Ahar Bank, and the monthly interest rate is stable at 20%."

"Wow," Irina said, holding the microphone in her hand and her expression of surprise, "My fans and I have found a new way to make money."

"But I don't recommend that you do that," Katie added, "I'm already planning to withdraw and leave."

"Why?" Irina asked curiously.

Katie winked cutely, "It's a secret."

When Irina wanted to ask something, Katie had already started giving interviews to other reporters.

Interestingly, a reporter behind Irina also asked a question about Ahar Bank, "Miss Katie, do you also think that Ahar Bank is at risk of a thunderstorm?"

"I'm a tennis player," Katie explained with a smile, "you're a sports journalist, don't cross the border to compete with financial journalists."

Zhang Jing was a little stunned six or seven meters away, looked at Ding Jiaqi and asked, "What the hell is Ahar Bank?"

"The situation here is a bit complicated," Ding Jiaqi introduced softly, "Ahar is called a bank, but you can't deposit money directly, the loan is very convenient, the disadvantage is that the interest rate is high, and the monthly interest starts at 12%."

Forgive Zhang Jing's limited knowledge, most banks are desperately trying to pull deposits, and for the first time in the world, I heard that some banks cannot deposit money directly.

Curious, Zhang Jing begged, "Jian Ming help me explain."

"Li Mingxiang, a stick man who graduated from Stanford's Department of Finance, created the Terre ecological platform system four years ago, and there are two virtual currencies under this platform, one is LUNA coin and the other is UST coin."

"You can understand LUNA as gold, UST as meter yuan, and Terre uses LUNA to achieve UST stability, creating three iron laws for this, one..."

"Wait," Zhang Jing interrupted Ding Jiaqi, "What does this have to do with the bank?"

"Brother Zhang," Ding Jiaqi spread her hands, "I'm trying to explain it in the simplest way, but I can't say a word."

"That's a little simpler." Zhang Jing requested.

Ding Jiaqi nodded, "The initial trading price of LUNA coin was less than 2.4 meter yuan, and then the price went all the way down, the currency price was less than 0.5 meter yuan for a long time, and it seemed to be only 0.1 meter yuan at the lowest time;

In order to stimulate the price of LUNA coins, Li Mingxiang has thought of many methods, such as application payment, game payment, scene payment, etc., but the effect is not ideal."

"Until Li Mingxiang founded the Ahar Bank, this bank only accepts users to deposit UST coins, because of the special relationship between UST coins and LUNA coins, when more UST coins are deposited in the bank, LUNA coins will decrease, and the price will start to climb steadily, and now it seems to have risen to 110 meters."

Zhang Jing's eyes widened, "from the lowest 0.1 meters to 110 meters!!

"Hmm," Ding Jiaqi nodded, "Li Mingxiang belongs to the category of geniuses, and can be regarded as a model for finance students."

"However," Ding Jiaqi said again, "Peel through the fog and look at the essence, Li Mingxiang is also playing to tear down the east wall and make up the west wall."

"If that's the case, why hasn't the price collapsed?" Zhang Jing

I don't understand asking.

"Because it is relatively reasonable," Ding Jiaqi stood beside Zhang Jing, watching Katie interact with reporters in a friendly manner, and introduced in a crisp voice: "Ahar Bank receives customer deposits in the form of UST currency banks, and pays 20% monthly interest to deposited customers, but can earn about 24% interest when lending out."

"How is that possible?" Zhang Jing questioned, "With such superb investment skills, why would he want to play with virtual currency?"

"It's possible," Ding Jiaqi analyzed, "First of all, borrowing, Ahar Bank requires customers to provide 200% collateral, the interest on the loan is 12%, and 12% is made from investment, and for some people to earn 12% return is not an exaggeration."

"Except for a few people who need money urgently, who would borrow 12% of the monthly interest?" Zhang Jing felt that his brain was not enough.

"In order to increase the number of borrowers, Li Mingxiang has another loan subsidy method, which is to be purchased with UST coins and LUNA coins, with an actual monthly interest rate of about 5%, and the gameplay is complicated, but I think that behind the complex gameplay, the behavior of demolishing the east wall and making up the west wall has actually happened, but it is not known."

"Why do you have this judgment?" Zhang Jing asked.

Looking at Katie, Ding Jiaqi picked her chin, "It was Katie who reminded me that because of the economic downturn, there are more and more people saving money, and fewer and fewer people borrowing money, and the price of LUNA coins under the Terre ecological platform is all supported by the lending of Ahar Bank.

Speaking of which, Ding Jiaqi himself was shocked, LUNA is the fourth largest virtual currency, and if something happens to it, the consequences will be catastrophic.

"What's wrong?" Zhang Jing asked his girlfriend with concern.

Ding Jiaqi quickly took out his mobile phone from his handbag, opened the options trading software, searched for the option information of Ahar Bank, and it was easy to see that someone had bought a large number of put options.

"Brother Zhang," Ding Jiaqi held up his mobile phone to explain, "someone is clearly shorting Ahar Bank, and it is not surprising that someone will sell a large number of UST coins for anchoring in the next two days, and the consequences may be unbearable for many people."

Just now, Ding Jiaqi explained that UST is similar to rice dollars, LUNA is gold, and the TERRE ecological platform uses LUNA to achieve UST price stability.

According to the three iron laws created by the founder, LUNA can rise indefinitely, while the price of UST can only hover around 1 meter, and the number of UST is not increased by artificial operation, and depending on the amount of LUNA, it passively increases or decreases, and ABAR Bank only accepts UST.

In order to maintain the stability of the UST price and indirectly support the price of LUNA, AHAR Bank needs to continue to lend out and create a profit of no less than 24%.

It sounds complicated, but it is also complicated in reality, Zhang Jing only needs to understand that Ahar Bank only accepts deposits in the form of UST currency, and does not care about anything else.

What Ding Jiaqi means is that if someone deliberately sells a large number of UST coins, the entire TERRE ecological platform system, including Ahar Bank, may flash crash.

"Is there a chance to make money?" Zhang Jing asked with concern.

Ding Jiaqi thoughtfully suggested, "Buying a b-bitcoin put option can maximize the benefits."

"Are these two things related?" Zhang Jing has a black question mark.

"The Terre ecosystem is the fourth largest cryptocurrency, and if something happens, Bitcoin will also fall. However, B-Tc is the largest, and if you buy two put options for one dollar, B-Tc will have a higher return."

"Try buying $8 million rice?" Zhang Jing tried to ask.

Ding Jiaqi reminded, "There may be a failure."

Because there is still a large amount of cash in the Mithril space, Zhang Jing can regard the risk as nothing, edit the message and send it to Barbie, instructing her to transfer all the available cash in the farm account to Ding Jiaqi for her to operate.
