Some people are saying it's okay to short altcoins with a -2% fee, usually just before a crash. Let me explain how fees work. After reading this, you might not dare to short Altcoin recklessly. The statement "extreme rates = impending collapse" is indeed true in certain scenarios. For example, if 50% of the spot market is about to be unlocked, and funds in the contract market are shorted first, the demand for short positions is greater than that for long positions, causing the rates to become extreme. Once the spot market is unlocked, the market will indeed collapse. However, for "monster coins," this fee rate is something that market makers can control. Let's first look at the formula for the rate: Contract fee rate % = Risk-free rate + Premium index. Premium index = (Mark price - Spot price) / Mark price. Therefore, applying the formula above, theoretically, if the premium of the contract mark price being lower than the spot price exceeds the risk-free rate, the fee rate will be negative. The contract mark price is affected by the contract's order book; theoretically, the greater the demand for short positions, the negative the fee rate, and the greater the demand for long positions, the positive the fee rate. (Important note: it's "greater demand," not "greater position size.") For example: If the spot price of a certain coin is 100 yuan, a long position in the contract places a buy order at 99.5 yuan (not daring to chase the price higher), and a short position in the contract places a sell order at 99 yuan (eager to dump the price). The actual transaction price is 99.25 yuan, which is lower than the spot price. Therefore, the fee rate is negative. This is an example of how the "high demand" for short positions leads to a negative fee rate. How does that cryptocurrency exploit short sellers using this rule? Suppose the market maker controls 99.99% of the spot market and wants to liquidate short positions. They build up enough long positions in low-priced contracts, and then push the price up. They can use a "small order book of long positions" to make the contracts fluctuate at high levels. As long as there are short positions open at the "current price", the contract price will be driven down sharply (because the order book of long positions is very thin). This will make the fees negative, and the short sellers will continue to pay the market maker's long position funding fees. Then the money earned from the funding rate is used to further drive up spot prices, thereby achieving the goal of further short selling. So what's the key point? 1. The fees aren't going to be pocketed by the exchange; they're going to your counterparties. 😅 2. The rate reflects the demand from both long and short positions, not the position size. 3. For cryptocurrencies prone to price manipulation, fee rates are not a good indicator of when they will crash. 4. The core of manipulating the market lies in absolute control of the spot market and a sufficient number of short sellers.

Thread
A few days ago, I discussed the topic of "How big is the AI market bubble?" with a friend. I'd like to share our discussion and then do some calculations together. First, let's roughly estimate the market size. Taking Chatgpt, which has the largest customer base, as an example, it currently has around 800 million monthly active users globally (covering 10% of the global population). Of these, 35-40 million are paying users. Let's take 37.5 million as the median, with most paying $20 per month. Assuming an average monthly revenue of $25, Chatgpt's annual revenue from its consumer-facing (C-end) market is $11.25 billion. Assuming that each of these 37.5 million customers pays for at least 3 AI services on average, the total C-end market size is $33.75 billion. (I think an average of 3 is a very optimistic assumption. As a heavy AI user myself, I currently pay for only 3-4 AI products, around $100 per month.) So, what is the market capitalization of the companies serving these AI C-end markets? Let's exclude the primary market (roughly estimated at around $1 trillion) and focus only on the seven major tech giants in the secondary market: Nvidia $4.4 trillion, Apple $3.9 trillion, Microsoft $3.7 trillion, Amazon $2.4 trillion, Google $2.4 trillion, Facebook $1.7 trillion, and Tesla $1.3 trillion. Except for Nvidia's $4.4 trillion market capitalization, which is purely AI-driven, the others' valuations are more or less not centered on AI. Assuming we only use 25% as the weighting for their AI market capitalization (I believe the actual premium for AI in the capital market is much higher than 25%, but for conservative estimates of a bubble, we'll use 25%), the result is $8.25 trillion (of course, there are many, many AI companies not included in this calculation, such as AMD, Palantir, Qualcomm, Oracle, etc.). $8.25 trillion divided by $33.75 billion = 244 times P/S. How do we understand this 244 times P/S ratio? We can refer to the P/S valuations of leading companies on March 24, 2000, the peak of the dot-com bubble. Amazon: 19x Cisco: 35x Qualcomm: 22x Microsoft: 26x IBM: 3x Oracle: 27x Intel: 16x After the dot-com bubble, most of these companies, even giants like Amazon and Microsoft, took 10-15 years to recover their 2000 bubble peaks. Of course, a P/S ratio of 244x doesn't necessarily indicate a large bubble in the AI sector. Currently, most AI revenue isn't from the $33.75 billion consumer market, but rather from "spending money on GPUs and infrastructure." Ultimately, these companies' investment in GPUs and infrastructure serves the consumer market, which, at least for now, isn't as large as many believe. The current dilemma facing the AI sector is that even though AI is quite usable, it remains a "production tool," not "productivity" itself. Therefore, AI service companies are still only paid for the "tool," but the capital market is valuing them based on the "productivity" narrative. What does this mean? If you ask a consumer or business owner to spend $50-$100 per month to equip their employees with AI, they're likely willing to spend that money, and that AI might indeed save the company the cost of one or two junior employees. But if you ask them to spend $2000-$3000, they're unlikely to be willing to spend that much. So even if the consumer market penetration rate increases tenfold to 375 million people (more than the US population of 350 million), a P/S valuation of 24.4x is still expensive in any industry. But who knows? Perhaps one day AGI will emerge, and AI will become productivity itself, and these AI companies won't be expensive anymore. Just like when we look back at 2000, were companies like Amazon, Apple, and Microsoft expensive? It's certainly much cheaper than it is now, but if you bought it in 2000, it would take 10-15 years to break even. And we don't know when AGI will arrive, or even if it will arrive at all. Let's just wait and see.
