**✅ 期权Carry的真相：Gamma=0、Theta=500，真的能每天稳收500吗？** 很多人以为： **Gamma≈0 + Theta=500** → 一天就能躺收500 Carry； **Gamma=0.0005 + Theta=0** → Carry ≈ ½×Gamma×S²×σ²×dt 就行了。 **但现实远没这么简单。** 这背后的坑，比初看深得多： **1. 卖出虚值期权临近到期，Deltaness越来越虚，IV反而趋势性上涨** 这不是均值回复，而是**系统性drift**。BS公式算的Theta衰减，会被这个漂移大幅侵蚀，必须提前扣除。 **2. 明明Long Gamma，对冲却经常高吸低抛？** 很大可能是 **Vanna在作祟**（Delta随IV变化而漂移）。如果对冲程序执行不够精细，没考虑Vanna、Charm等高阶Greeks，就很容易把本该通过Gamma scalping赚到的利润亏掉。 **你有没有注意到这些异常？** 这些执行偏差，也要从MTM Carry中扣除。 **3. 真实交易成本无处不在** 期权/期货re-hedge时的**滑点 + 手续费**，在高频调整下会持续侵蚀理论Carry，尤其在crypto流动性碎片化的市场。 --- **真正的Carry应该这么算：** **True Carry = MTM Carry（逐笔Mark-to-Market累积盈亏）** **- Shape TS Roll（波动率期限结构滚动损益）** **- Directional（残余方向性暴露损益）** **- (Fees + Slippage)（手续费+滑点）** 只有把**理论 snapshot** 还原成**真实逐帧MTM**，再扣除期限结构漂移、方向性泄漏和摩擦成本后，你才能看到策略的**净边际**到底是正还是负。 **简单Greeks看一眼舒服，但真金白银要靠MTM+全维度分解。** GreeksLive的新系统即将上线，帮大家把这一切算清楚——从tick级回放、到真实Carry拆解，一站式搞定。 **Special thanks to our Quant！@StochAlex07 **

LATEST: 🇺🇸 Former US Defense Secretary Mark Esper called the CLARITY Act a "national security imperative," arguing American leadership in financial technology is at stake.

A key breakthrough for global fusion research. On July 28 local time in France, the sixth vacuum vessel sector module of the ITER tokamak was successfully hoisted and precisely positioned, bringing the total module assembly progress past the two-thirds mark. Led by the CNNC Engineering Consortium, the international team completed the nearly 30-hour continuous operation with zero safety and quality incidents, continuing to contribute Chinese expertise to this landmark global scientific collaboration.

$1.6 million dollars in Bitcoin was drained from my account on July 29th in the Cold Card wallet hack. My Bitcoin was in cold storage. My keys were on a ColdCard device kept in a safety deposit box that had never been connected to the internet. This part's nerdy, but here's what happened: Hackers discovered a vulnerability in the part of the hardware wallet code used to create seed phrases. This allowed them to use AI to brute force guessing seed phrases. I was at our cottage and heard about the hack today. "No way this affects me." I thought. I logged into Wasabi––software that lets me view my bitcoin wallets online. Right away I saw lines of red transaction–withdrawals–and I knew. From 9:36pm - 9:43pm on July 29th, every wallet I had had been emptied. 18.25245043 btc gone. That's just over $1.6 million dollars CAD. Perhaps the hardest part about this is that I did everything right. I never shared my seed phrase with anybody. My devices never touched the internet. Everything was kept in multiple safes and safety deposit boxes. None of it mattered. All because the hardware that created the seed phrase originally had one line in their code from 2021 that had a vulnerability. I'm filing a police report and a report with the Ontario Securities Commission. But I don't expect to recoup anything. A part of me is trying to make sense of what just happened. Or try to figure out a lesson in it. I'm struggling. $1.6 million is a staggering amount of money to have stolen. I guess all that I can think about right now is that I'm so damn happy that I'm an entrepreneur and that my earning potential is under my control. Mark my damn words. I'll recover.

One of the best parts of my trip to Japan was getting to meet so many friends from the Renaiss community. 💜 Thanks our boss @Plus_Ultra_715 for treating us to delicious foods~ Glad @SiNaToDdFelix, @corang_ee, @lilyuzuu, @harryinhk ,@StephenSu9527, @wonnie ,@Mark_Memelord, @snoopylee115 joined our Renaiss lunch. It was so nice spending time talking about collectibles, cards, and everything with each other. After lunch, we headed to Akihabara together to check out some card shops. Huge thanks to @wonnie for inviting me to open a pack… and somehow I pulled Nami! ✨ Collecting has never been just about owning a card. It’s about the people you meet, the memories you make, and the connections you build along the way. Thank you to everyone who made this Japan trip so memorable, and creating these moments with Renaiss. Looking forward to seeing Renaiss community in another region! @renaiss_cmty @renaissxyz
