Coin Mechanics

It was my mistake. I forgot that some people might have no idea what "Party A" and "Party B" are. Oh well, this time I'll just use grocery shopping, something even elementary school students can understand, to explain the principle of a coin. If anyone still can't understand this, then I can only question their comprehension abilities...

First, it's important to understand that the ability of the Phantom Coin is "guaranteed"; there's no probability involved. Aside from specific elements, Tag, or abilities (such as being unaffected by other Phantom Object, being untargetable by other Phantom Object, or being able to nullify other Phantom Object' abilities), there are only two possibilities that could cause its ability to fail: insufficient stock or insufficient funds.

It's like opening a business; you can't refuse to do business with reasons like "you're too ugly," "I'm in a bad mood," or "I just don't want to do business with you," right? That's not a transaction; that's picking a fight.

The lack of goods is easy to understand. If the vegetable seller has sold out of radishes, you can't buy radishes from him no matter how much money you offer, so the transaction will fail. (The transaction you propose must be something the other party can actually do.)

If you don't have enough money, it's simple. For example, if radishes cost one yuan per pound, and you only offer fifty cents, the vegetable seller can naturally refuse to sell to you. (The implicit value of a coin is higher than the other party's price for the transaction.)

Then there's the issue of price increases and decreases:

Snow and freezing temperatures cause vegetable prices to rise. If you insist on buying at the original price, the seller may refuse to sell to you. Similarly, vegetables that are not fresh will cause prices to fall. (Objective reasons can cause value to rise or fall, but the condition that "the transacting party is aware" must be met. For example, if the seller is completely unaware of the snowfall, the price cannot be increased because of the snowfall. Likewise, if the seller is unaware that the vegetables are not fresh, the price will not fall.)

At the same time, vegetable vendors cannot raise prices based on reasons such as "I'm starving," "My child needs a lot of money for school," or "Your appearance has caused me emotional distress." (The buyer cannot raise prices based on their own subjective reasons.)

However, if the buyer and seller are acquaintances and understand each other's family circumstances, Play the Victim can increase the price. But what increases the price here is not the Play the Victim itself, but the "relationship" between the two. (The trader can raise the price if they understand and agree with the tradee's subjective reasons; "agreement" is the key.)

As for why the traded party can independently determine when the transaction is over...

This is because the trader did not specify the details.

Just like when you're buying vegetables, if you simply tell the vendor, "Give me three yuan's worth of radishes," then you pay three yuan, and the vendor gives you radishes, but how much they give you is up to the vendor's own pricing.

The protagonist says "keep quiet," but doesn't specify how long that silence will last. Jessica will decide the duration based on her own "pricing." Furthermore, because the transaction is ongoing, Jessica can proactively stop when she feels it's not worthwhile. In other words, theoretically, it's possible to stop the transaction the instant you feel it's not worthwhile, but this presupposes that the person being transacted with subconsciously believes that "keeping quiet for even a moment is worth $100,000."

However, because there is no "bargaining," the party being traded will be Full Heart, Full Mind.

Then there's the matter of the transaction details.

The simpler the trade, the more accurately it can be executed; conversely, the more complex and ambiguous the statement, the greater the room for maneuver for the trader.

Just like in design, the broader the requirements, the more room the designer has to maneuver. But here's a situation different from the client-vendor dynamic in reality.

That is, unlike in reality where the client can infinitely request a rework, in transactions conducted through trading coins, as long as the contractor's performance meets the terms of the transaction, the client must pay again if they want a rework.

This is like asking a vegetable vendor to chop scallions into small pieces. After that, you might want scallion segments instead. The vendor certainly won't give you a refund for the chopped scallions; instead, they'll make you pay for more scallions before they'll chop them for you.

Finally, let's talk about pricing.

Pricing is based on common sense and the perception of the person being traded. For example, a destitute person might think, "100,000 is enough for me to sell my life," so his life would be priced at 100,000. When the transaction occurs, a single coin can buy his life.

Regarding the issue of price gouging, please refer to the above discussion on price increases and decreases.

In other words, if this poor person happens to receive a commission to buy a kidney, and can sell his life for a higher price (objectively), he can refuse the transaction on the grounds that "he doesn't have enough money," provided that the transaction party knows that selling a kidney can earn more money.

However, if his reasons are simply "I changed my mind," "I'm scared," or "I want more," he cannot influence the transaction.

In short, the coins printed by the protagonist are Phantom Object that embody the concept of "everything is tradable" based on the commercial social system. In essence, "everything has a price," and there is only what one can afford or not afford; there is nothing that cannot be bought.

The so-called "I'd rather die than do [that]" is simply because the psychological price is high enough, exceeding the price one would normally pay for their own life.

Well, this isn't about my values; it's just describing the essence of this Phantom Object.
