The 3 biggest things to talk about in AI today!
1️⃣ Apple released an App Intents update, allowing all developers to make their apps’ features available for Siri AI to use, supporting cross-app actions and including a subset of the Agent Skill format. Developers can start testing it with the iOS 27.3 beta.
2️⃣ Anthropic launched the Personal Finance feature in Claude. Pro, Max, and Ultra users in the U.S. can begin beta testing it this week. It connects to bank and card accounts via Plaid in read-only mode, allowing users to query spending categories, bill reminders, and unusual charges in nat

Qwen has landed Apple Siri, and personal agents are about to face a crushing blow from operating systems.

Grok Bot plus Feishu for work-related automation.
Today AI helps me check the weather, monitor my personal health data, and see what fun things there are to do around Shenzhen.
Perfect division of labor.
I used to use a Mac mini plus Feishu as a 24-hour personal assistant, but now software can completely replace it, and there’s no need for local deployment anymore. Feels like the Mac mini was kind of a waste.

Kuku got their Hong Kong bank card restored and subscribed to X Premium! I can finally ramble to my heart’s content and try out Grokbot, too.
I finalized my business trip plans today. I’ll briefly experience all four seasons this week, and I’ve also made plans to eat with friends—can’t let a single meal go to waste. My Halloween weekend is packed, too, so I can finally experience the Halloween atmosphere in Hong Kong.
I spoke with the platform about recent campaigns over the weekend. I’ll update things ASAP tonight so I don’t miss out on this round of support.
Take things one step at a time, a

Hosting AI meetups at bars is such a great format. When people are a little tipsy, they’re less guarded.
Today, several business models I’d previously envisioned were debunked, and someone pointed me in the right direction.
Shenzhen entrepreneurs are so generous, sob, and the vibe is amazing🥹 Spending a little time chatting with them makes me feel like I’ve studied myself silly.

Commemorating the end of a two-year relationship.
From now on, my principle is to treat myself well without limits!
Treat yourself so well that others curse you for being so selfish—that’s when you can say you’ve slightly achieved your goal.
Always remember today’s shock and pain. Any hormone-fueled sacrifices will automatically be classified as having been wasted on the dogs; there’s no need to dwell on them.
I have a feeling my career is about to take off! Now that I’m no longer confined to a relationship, I feel even more motivated to explore the world! Awesome

I've been observing my trading records lately and realized that many strategies are run based on intuition without systematic backtesting data support. When profits come, I can't tell if it's truly skill or just luck; when losses happen, I also can't tell if the strategy has failed or if it's just normal drawdown. Honestly, this kind of uncertainty is quite anxiety-inducing — your trading system is actually built on quicksand.
As someone mainly selling options, I really understand this feeling. Collecting premiums every month seems stable, but I've also experienced extreme market conditions

I've been observing the data changes in the options chain recently and found it really exhausting to manually monitor the Greeks values of dozens of contracts. IV is fluctuating, Delta is changing, and tracking the increases and decreases in open interest in real-time is also quite difficult. Honestly, this kind of monitoring can be pretty stressful—you know the data is changing, but your brain simply can't process so much information.

As someone who sells multiple contracts at the same time, I can really understand this feeling. Staring at the screen, refreshing every few minutes, afraid of

BTC has been hovering around the 74K level for a while. The Federal Reserve's interest rate decision is like a sword hanging over everyone's head, and the market is choosing to stay on the sidelines, waiting for the dust to settle.
This kind of market situation is somewhat awkward for spot holders. The price hasn't fallen, so they are reluctant to cut losses and exit; but it hasn't risen either, so capital is stuck here, unable to enjoy the benefits of an upward move, while also bearing the cost of time. If both bullish and bearish views lack confidence, it seems like there's only waiting to

In recent market conditions like this, many spot holders can only watch their accounts shrink, but people who understand options are already setting up Put Spreads to collect premiums.

A Put Spread, simply put, means selling a Put while buying a lower strike Put for protection. For example, with BTC currently at $70K, you could sell a $68K Put while buying a $65K Put.

The core logic is: if BTC drops to between $68K-$65K, you profit from the premium difference. If BTC breaks below $65K, your maximum loss is locked in at the difference between the two strikes minus the premium collected. If BT

In ranging markets, trend traders suffer the most, but for option sellers, it's the best environment.

The math behind it is simple:

Option pricing is based on the Black-Scholes model, where implied volatility (IV) reflects the market's expectations for future volatility. But historical volatility (HV) is what actually occurs.

90% of the time, IV > HV. What does this mean? The market consistently overestimates future volatility. As a seller, you're essentially selling this overestimation.

Take BTC as an example right now. IV might be pushed higher by various macro news, but if the actual mo

I've been thinking about a question lately: Why do some people have a clearly better experience holding positions during BTC's volatile swings, while others struggle?

After observing, the answer often comes down to whether they're using options tools. With BTC currently hovering around $70,000, having retreated over 30% from its all-time high of $109,000, this consolidation phase after a high-level pullback is actually the most psychologically challenging stage for position holders. Spot holders easily lose patience amid repeated fluctuations, futures traders face liquidation risks, while tho

I've been closely monitoring BTC's price action lately and noticed it's been hovering around a key resistance level for several days now, with trading volume gradually contracting. To be honest, this kind of market condition is pretty anxiety-inducing — the market is waiting for a clear directional signal, but nobody knows when that signal will actually arrive.

As someone holding spot positions myself, I can really relate to this feeling. Capital is tied up there, and every day you watch the price fluctuate without generating any meaningful returns. This waiting period is actually quite drain

# Options Market Heats Up at Month-End

The options market is always particularly active at the end of March. This month, on the 27th, a large batch of BTC options will expire, reportedly accounting for over 40% of total open interest.

These large-scale expiration events typically bring extra price volatility before and after expiration, as market makers need to hedge their Gamma risk, and many traders will choose to roll positions or close them out. Current total open interest is approaching 500,000 contracts with a notional value exceeding $36 billion—this scale is already substantial enoug

# Recent BTC Market Shows Typical Directional Uncertainty

The recent BTC market is displaying typical characteristics of directional indecision. Price action is oscillating within a range, with bullish and bearish forces achieving a temporary equilibrium. This state may persist, or it could be broken at any moment.

For options traders, this is precisely when strategy diversification can demonstrate its advantages.

In an environment of directional uncertainty but reasonable volatility, straddles or wide straddles are common choices. Simultaneously buying calls and puts, the bet is on volatil
