About Me

In Singapore

Hello, I’m Daniel. Some call me Sangyoon. I was born in the States, but spent most of my life in South Korea and Singapore. I came back to the U.S. for college where I graduated from NYU Stern with a BS in finance.

After interning at a couple funds and doing a brief stint in investment banking, I moved to San Francisco and did a startup where I 1) arbitraged inefficient markets in crypto and 2) made a crypto price-tracker and wiki platform.

While I have a day job now, I continue coding things at night.

At college in 2015. Fellow co-presenter here is now founder of Multicoin Capital, one of the world's top crypto hedge funds. Who would've thought back in 2015!

I like playing poker, and used to go to Vegas a lot. I also enjoy golf like every Korean.

Investments

How To Intelligently Invest in Crypto as a Retail Investor (from a VC)

Don't be a speculator. Be an investor.

I go over two big wins and try to illuminate the process behind finding winners early.

Reflection On My 2020 Investments - Bitcoin, Baidu, Cross-Harbour Holdings, and Cinemark

This is a recap of my largest concentrated positions in my personal portfolio, and how they have performed

I like having a concentrated portfolio. My biggest holdings through 2020 were Bitcoin, Baidu, Cross-Harbour Holdings, and Cinemark.

Fundamentally Valuing Uniswap

Valuing the top decentralized exchange

Here is how I valued Uniswap. My analysis here is conservative because I haven't accounted for the utility value of tokens, but only the cash flow potential.

Fundamentally Valuing Maker DAO

Valuing the iconic stablecoin

Here is the framework I used to value the MKR tokens.

A Stock Trading Below Net Cash Balance — Cross-Harbour Holdings (0032: HK)

Extremely undervalued sum-of-the-parts play with a large margin of safety, trading below net cash & investments

Investment Thesis: The company is currently trading at a massive 30% discount to the value of its net cash and investment portfolio. By buying at the current price you effectively 1) own the current net cash position at 70 cents on the dollar, and 2) get its operating businesses for free, all of which generate stable free cash flow.

Valuing the Next Billion Dollar Search Engine - DuckDuckGo

How DuckDuckGo has room to grow into a $1B+ valuation despite Google

I predict at least a 5x gain, and up to 30x increase from its rumored valuation of $160M in late 2018. I want to emphasize that DDG does not have to become the next Google — this investment is suitable for a series B or C investment for a good risk adjusted return.

Fundamentally Valuing Bitcoin at $75,000 / BTC

A framework to value BTC for the fundamental investor

I claim that: 1) Bitcoin has negligible intrinsic value without mainstream use as a transactional currency, 2) that despite this, Bitcoin can still hold value based on a different valuation model, 3) a valuation of Bitcoin, and 4) how a cryptocurrency like Facebook’s Libra affects Bitcoin’s valuation.
