Vitalik Buterin

Buterin''s personal investment approach is deliberately simple and aligned with his own creation. He holds primarily ETH and has been transparent about not trading actively or making complex financial moves.

He donated a substantial portion of his meme coin holdings — including a SHIB donation to the India Covid-Crypto Relief Fund that was worth about $1 billion on paper, though the fund realised closer to $400 million once it actually sold — when developers sent him tokens to increase their perceived legitimacy. He has said he does not feel entitled to wealth beyond what he needs to live and fund work he cares about.

Arianna Simpson

Simpson invests in crypto the way a founder would, not a spreadsheet jockey. She hunts for the technology that developers actually want to build on.

Then she bets big and holds through the wild swings. She is comfortable being early.

She is comfortable looking wrong for a while. As she puts it, the job is to follow where the best entrepreneurs are already going, not to sit in a room and decide what should be interesting.

In plain English, she buys the picks and shovels of crypto and waits years.

Vitalik Buterin

Buterin believes that decentralized systems — where no single entity can control, censor, or inflate — create better outcomes for society than centralized ones. His philosophy extends beyond money to governance, identity, and social coordination.

He has written extensively about "credible neutrality" — the idea that a system is most valuable when no participant can manipulate it for their own benefit. He is genuinely trying to build infrastructure for a more fair and open world, not just technology for technology''s sake.

Arianna Simpson

Simpson's core belief is that crypto matters most where money is broken. She points back to Zimbabwe.

When your currency loses value by the hour, a network no government controls stops being a toy and becomes a lifeline. She bets on that idea over decades, not quarters.

She also backs builders over hype. The projects that survive are the ones developers keep showing up to work on, bull market or bear market.

Her best investments, she says, are the ones where the founder's thinking is further ahead than her own.

Vitalik Buterin

Buterin''s financial risk is concentrated entirely in the crypto space — primarily ETH. He has experienced 80%+ drawdowns in ETH price multiple times and continued working regardless.

He is not a risk manager in the portfolio sense. He is a technologist whose compensation happens to be denominated in a volatile asset.

His approach to personal finances appears to be minimal engagement rather than active management.

Arianna Simpson

Simpson is built for crypto's stomach-churning drops. She thinks in decades, not weeks, so an 80% crash reads as noise rather than an emergency.

She proved it the hard way. Autonomous Partners was investing right as the 2018 crypto winter hit, and she kept going.

Her funds are designed to be 10-year-plus funds on purpose. The whole point is to hold long enough that short-term panic stops mattering.

Vitalik Buterin

Buterin lives extremely modestly for someone with a net worth exceeding $1 billion. He has stated his annual personal spending is approximately $100,000.

He rents rather than owns. He does not own a car.

He travels extensively but simply. He donated the majority of the meme coins he received to charity rather than selling them.

He has stated publicly that he does not want to become a billionaire philanthropist in the traditional sense — he wants to stay involved in technical work.

Arianna Simpson

Simpson keeps her personal life almost entirely offline, which is rare for someone this visible in crypto. What is public is how she handles the asset itself.

She is a holder, not a day trader. She has said the firm's funds are built to run for a decade or more, and she invests her attention the same way.

For someone whose whole job is digital assets, she treats them less like a casino and more like seeds planted for a long harvest.

Co-founding Ethereum is the win, full stop. The network processes trillions of dollars in transaction value annually.

It enabled DeFi — decentralized finance, a parallel financial system built on smart contracts. It enabled NFTs — however one feels about them.

It enabled DAOs. It is the infrastructure layer on which most of the innovative blockchain applications since 2015 have been built.

Its market cap has exceeded $500 billion. He created this at 20.

That is the win.

Phantom. Simpson got in early on the crypto wallet, and a16z crypto backed it when it was a small team building on Solana.

Phantom raised $150 million in January 2025 at a $3 billion valuation. Her other headline deal was a wild ride.

She led the $152 million round in Sky Mavis, the maker of Axie Infinity, in October 2021 and joined its board. Months later the game's Ronin bridge was hacked for about $600 million and the token collapsed.

Phantom is the win. Axie is the reminder that crypto giveth and taketh away.

Vitalik Buterin

The DAO hack of 2016 is the most consequential crisis Buterin has navigated. The DAO — a decentralized autonomous organization built on Ethereum — was hacked for $60 million in ETH shortly after launch.

Buterin helped lead the decision to hard fork the Ethereum blockchain to reverse the hack, which was philosophically controversial: the entire point of "code is law" in blockchain is that transactions are irreversible. The fork split the community, creating Ethereum Classic as a separate chain.

It was the right pragmatic decision and the wrong philosophical one — a tension Buterin has never fully resolved.

Timing. Autonomous Partners launched in late 2017, right at the peak of the crypto mania.

Within months the market fell off a cliff. Bitcoin dropped from nearly $20,000 to around $3,000 by the end of 2018.

Being early is one thing. Being early and then watching the entire market crater tests everyone.

The rough entry taught her a lesson she now lives by. Conviction only pays if you can survive long enough to be proven right.

Vitalik Buterin

Buterin was born in Kolomna, Russia, in 1994 and moved to Canada with his family at age six. His father was a computer scientist, and Buterin showed early mathematical gifts.

He discovered Bitcoin at 17 through his father and became obsessed — writing for Bitcoin Magazine starting in 2011 as a teenager, developing a reputation as one of the most thoughtful analysts of the nascent blockchain space.

He proposed Ethereum in a 2013 whitepaper, arguing that Bitcoin''s scripting language was too limited and that a more general-purpose blockchain — one that could run arbitrary programs called smart contracts — would unlock far more value. He was 19.

Bitcoin''s developers declined to implement his ideas, so he built Ethereum separately. He received a Thiel Fellowship in 2014 and dropped out of University of Waterloo to launch the project.

Ethereum launched in 2015. It became the second-largest cryptocurrency by market cap and the foundation of DeFi, NFTs, and most blockchain applications built since.

Arianna Simpson

Simpson grew up in Milan and studied international politics at Penn State. Her turning point came in Zimbabwe in 2013.

She saw firsthand what happens when a currency loses value by the hour. That got her hooked on the idea of money no government can print at will.

She quit her job at Facebook and joined BitGo, a company that guards crypto for big institutions. In 2015 she helped start Crystal Towers Capital, backing young Y Combinator startups.

In 2017 she launched her own crypto fund, Autonomous Partners. She raised it from serious names, including Coinbase CEO Brian Armstrong and David Sacks' Craft Ventures.

In 2020 she joined a16z crypto as a deal partner and was later made a general partner.

Ethereum Foundation is the non-profit organization that funds core Ethereum development. Buterin is the most prominent figure associated with it but is not its CEO — he functions more as its chief architect and public intellectual.

He has no formal ownership of Ethereum the network. It is decentralized.

He holds Ethereum tokens (ETH) that he has accumulated since the genesis block.

He has also written extensively for the Ethereum blog and his personal blog (vitalik.ca), which covers cryptography, mechanism design, social coordination, and political philosophy. His blog posts are read by thousands of researchers and developers.

He serves on the boards of several organizations in the blockchain space.

Arianna Simpson

Autonomous Partners was her own show. She started it in 2017 and used it to back crypto projects like Talos, a trading platform, and Mythical Games, a blockchain gaming studio.

At a16z crypto she now helps run one of the largest crypto funds on earth, more than $7 billion across several funds. Her best-known bets there are Phantom, the crypto wallet, and Blackbird, the dining rewards startup from Resy co-founder Ben Leventhal.

She also sits on the board of Sky Mavis, the company behind Axie Infinity. Before all of this she worked at BitGo and Facebook.

Vitalik Buterin

University of Waterloo, Computer Science — dropped out in 2014 after receiving a Thiel Fellowship. He has said the fellowship gave him the financial runway to work on Ethereum full time at a moment when the project would otherwise have been impossible to pursue.

Arianna Simpson

Simpson went to Penn State, in the Schreyer Honors College. She earned dual degrees in international politics and Spanish.

Not a computer science degree. Not an MBA.

Her real education in money came later, on the ground in Zimbabwe in 2013, watching inflation do its damage in real time.
