How the NVDA Strategy Became the Backbone of Our Stock Portfolio

The NVDA strategy didn’t start as a master plan. It emerged out of necessity.About a year ago (2025), after the DeepSeek-related volatility shock that briefly crushed NVDA and other AI names, our stock portfolio was under pressure. I was using margin across multiple positions, volatility expanded fast, and I faced a margin call. That was the moment I decided to abandon complexity and build the entire portfolio around a single, highly liquid…

Bots, Rewards, and TerraM: Unexpected Signals from DeFi Liquidity

I minted 10,000 TerraM tokens back in 2022 with a very simple idea: raise $10,000 and trade Ethereum options. The plan was straightforward - tokenized participation, transparent backing, real trading activity. In practice, the initial capital raise never really materialised. There was no big launch, no rush of external capital, no instant liquidity.What did happen over time, however, turned out to be more important.Instead of relying on outside…

Hiking to Turtle Lake: A Winter Trail in Tbilisi

Embedded thumbnail for Hiking to Turtle Lake: A Winter Trail in Tbilisi

Last Sunday we did a hiking trip to Turtle Lake, starting from the stairs on Polikarpe Kakabadze street. I’ve been a big fan of hiking in Tbilisi for a long time. More than ten years ago, we used to do hiking trips almost every weekend, something I’ve written about on the blog many times. Back then it was routine.Last chance workout on the trails around Turtle Lake before Tbilisi MarathonHiking trails near Turtle lake, Tbilisi in WinterRemote…

How to Borrow Against Solana on Bybit to Boost Covered Call Income

On September 4, 2025, we launched the Solana Covered Call Growth Fund at Terramatris. The fund’s objective is to grow our SOL holdings primarily through selling covered calls, with most initial positions entered via cash-secured puts.Although the fund is still small, over time we accumulated 6 SOL from option premiums. This led me to explore a leverage extension: using earned SOL as collateral to borrow stablecoins, acquire additional SOL, and…

Week 42 / $107 Options Income From Rolling NVDA Credit Spreads During the Greenland Shock

As of January 23, 2026, our covered-call stock portfolio has dipped slightly by -0.43% and closed at $10,788.The previous week was highly turbulent. As the market opened on Tuesday, NVDA briefly dipped below my call strike levels. Given the elevated volatility, I decided not to wait and took an early roll, pushing the position several weeks (February 6) out to reduce near-term risk.Volatility remained elevated throughout the week and only began…

Week 41 / NVDA Credit Spread Strategy: 0.43% Weekly Return if Expires Worthless

Greetings from Tbilisi. After more than three weeks in India, we are finally back—welcomed by temperatures below 0°C and already missing Goa and its +31°C.Last week, we also held our annual office party (Caucasus Translations) at Babilo Music Hall, enjoying excellent Georgian cuisine, wine, and traditional Georgian dance. I skipped the food due to intermittent fasting (no eating after 14:00), but it was a great evening nonetheless.As of January…

TerraM 52‑Week Saving Challenge: Commitment, Liquidity, and Skin in the Game

I have attempted the classic 52‑week saving challenge several times over the years. I tried it with cash, mutual funds, and even speculative assets like meme coins. Results were mixed. Sometimes the discipline worked, sometimes it failed -  usually not because of returns, but because of inconsistency and lack of long‑term conviction.This time, the setup is different.I am launching the TerraM 52‑Week Saving Challenge, centered entirely on…

Week 40 / NVDA Strategy, $65 Premium Income, and Margin Reduction

Greetings from Mumbai, India. For the past three years, we’ve spent our winter holidays in India, usually traveling to Goa via New Delhi. This time, however, we arrived and departed through Mumbai and had a few days to explore the city. I’m genuinely impressed. Mumbai is definitely a city where I could imagine living long-term. Beyond that, it stands out as one of Asia’s major financial centers.One thing that really stands out when traveling…

Exploring Crypto Spread Trades With India: Lessons From the Kimchi Premium

The idea of regional crypto arbitrage isn’t new. The most famous example remains the Kimchi Premium — a persistent price gap where Bitcoin and stablecoins traded at a premium on Korean exchanges due to capital controls, retail demand, and limited outbound liquidity.India occasionally shows similar characteristics. During a recent vacation in Palolem Beach, Goa, I found myself regularly exchanging USD to INR at beach shack money changers. That on…

Week 39 / Road to $25K: Rolled Up and Forward NVDA Covered Call, Adjusted Credit Spread

Greetings from South Goa, Palolem Beach, India. I hope you had a great New Year’s party - we certainly did.As of January 2, 2026, our covered-call stock portfolio has decreased slightly by -0.84% and closed at $10,607. For the sake of transparency, it’s worth noting that the slight decline is due to USD/EUR exchange rate movements. The U.S. dollar appreciated modestly against the euro, which reduced the total value when expressed in EUR and back…

Why I Don’t Like Selling Credit Spreads Without Owning the Underlying Asset

Credit spreads are popular for a reason. They look elegant on paper: defined risk, high probability, steady income. I trade them myself -  regularly. But over the years, one conviction has become very clear to me: I do not like selling credit spreads (or iron condors) on assets I’m not willing to own.This is not a theoretical opinion. It comes from real trades, real stress, and real tail-risk events.A few years ago, I was actively trading 0…

Week 38 / Road to $25K: Closing 2025 Above $10K with Covered Calls and NVDA

Greetings from India. This holiday season we’re in South Goa, staying near Palolem Beach — our third year in a row returning here. With temperatures above 30 °C and Kingfisher beer under $2 per bottle, the place is hard to beat. With a portfolio our size, one could comfortably enjoy life here living off options income alone.That said, As of December 26, 2025, our covered-call stock portfolio has grown by an additional 2.21% and reached $10,…

Chhatrapati Shivaji Maharaj (Mumbai) International Airport

Mumbai airport

Chhatrapati Shivaji Maharaj International Airport is the international airport serving Mumbai, the capital of the Indian state of Maharashtra. It is the second-busiest airport in India in terms of total and international passenger traffic after Delhi, the 14th-busiest airport in Asia, and the 31st-busiest airport in the world by passenger traffic in 2024.I first arrived at Mumbai’s Chhatrapati Shivaji Maharaj International Airport  at the…

Gateway of India, Mumbai

Gateway of India

I first visited the Gateway of India at the end of December 2025, during our three-week trip to India. We spent only a few short days in Mumbai, and this stop was not planned in any deep or academic way. We arrived from The Lalit Hotel by Uber — roughly a 28 km drive, costing under 700 Indian rupees. At that point, I had only a vague idea of what the place was, and almost no sense of its symbolic weight.At first glance, it felt like another…

Road to a $25,000 Stock Portfolio with Options Trading

With the new year of 2026 fast approaching, I’ve decided to start another challenge.This one is deliberately smaller than my previous ambitions of building a $100K or even a $1M portfolio. Not because those goals are impossible, but because this time I want something more contained, measurable, and—hopefully—easier to execute with discipline.By the way, I should clarify one thing. I first reached a $25,000 net worth back in 2019. …
