What Cryptocurrency Are Billionaires Buying?

Forget the meme coins and the 100x lottery tickets. I’ve been tracking billionaire wallet activity and public filings for close to a decade, and the truth is surprisingly boring: most billionaire crypto exposure boils down to two assets — Bitcoin and Ethereum.

But that doesn’t mean there aren’t interesting nuances. While some billionaires dabble in high-risk altcoins, the vast majority are accumulating digital assets the way you’d expect a seasoned investor to behave: cautiously, methodically, and with extreme patience.

Why Do Billionaires Prefer Bitcoin?

Bitcoin is the only cryptocurrency with a truly global network effect. It’s not run by a foundation, it doesn’t have a marketing team, and it’s been around long enough that institutional money finally treats it as an acceptable balance-sheet asset. Bloomberg has tracked the rise of corporate Bitcoin treasuries for years, and the trend continues.

Think about Michael Saylor’s MicroStrategy. That company built an entire treasury strategy around Bitcoin. Every single regulatory filing shows the same pattern: buy, hold, repeat. Saylor doesn’t trade in and out. He famously views Bitcoin as a “100-year store of value.”

I once had a mentor who ran a multi-family office in Geneva. He told me that Bitcoin is the only crypto his clients ask about by name. “They don’t care about gas fees or latency. They care about who controls the ledger,” he said. That resonated with me. Bitcoin’s decentralization is its killer feature.

There’s also the so-called “cold storage” effect. The most sophisticated investors I know never leave Bitcoin on exchanges. They use hardware wallets and deep-cold storage protocols. That alone tells you they’re building long-term positions, not looking to flip in the next bull run.

I often get asked whether billionaires are selling Bitcoin for altcoins. The data says no. In every market cycle, Bitcoin’s dominance among the top 100 crypto addresses remains above 60%. That’s from public on-chain analytics. Altcoins come and go, but the “holy grail” remains Bitcoin.

What Altcoins Are Billionaires Buying?

Bitcoin gets the lion’s share, but it’s not the whole story. A handful of altcoins show up repeatedly in billionaire portfolios. Let’s break down the main ones.

Ethereum (ETH)

Ethereum is the #2 cryptocurrency by market cap, and for good reason. It’s the heartbeat of decentralized finance (DeFi) and non-fungible tokens (NFTs). Billionaires like Mark Cuban have openly discussed holding Ethereum as part of their core strategy. Business Insider has covered Cuban’s commentary on Ethereum multiple times.

Cuban has talked about Ethereum’s flexibility — smart contracts, staking, and its developer ecosystem. For him, Ethereum is more like a “software company” than money. And the merge to proof-of-stake changed the risk profile, which made it even more appealing.

In my own research, I’ve noticed a pattern: billionaires who understand technical infrastructure tend to prefer Ethereum. It’s not just a bet on price; it’s a bet on continued developer adoption.

Ethereum’s shift to proof-of-stake also opened the door for institutional staking. A few billionaire family offices I know are earning yield on their ETH through regulated staking pools. For them, ETH is not just a speculative bet; it’s an income-generating asset.

Let me give you a concrete example: I remember watching a private fundraising demo in San Francisco where a startup used Ethereum smart contracts to automate royalty payments. The investors in the room were all accredited and high net worth. One of them quietly mentioned that he’d shifted a significant chunk of his personal crypto from Bitcoin to Ether “because of the network activity.”

Solana (SOL)

Solana is the one high-risk altcoin that shows up more than any other in serious conversations. Why? Speed. Lower fees. High throughput. Retail crypto users love it, and a few prominent investors — like Sam Bankman-Fried before his downfall — were vocal supporters. But note: even with the FTX drama, Solana has managed to survive and institutional money trickled back in.

I have mixed feelings about Solana. It’s technically impressive, but it’s had network outages. Billionaires who do buy it usually allocate a small percentage, never more than 5% of their crypto portfolio. That tells you everything about how they perceive risk.

Here’s a rule of thumb I use: if a billionaire mentions an altcoin in a podcast, they probably hold a tiny bag for “innovation” purposes. Don’t confuse that with deep conviction.

Other Altcoins on the Radar

Beyond ETH and SOL, you often see small allocations to things like Chainlink (LINK), Aave (AAVE), and occasionally even Dogecoin. Yes, Dogecoin. Elon Musk never sold his stash, I’m pretty sure. But don’t confuse meme coins with serious positioning. Billionaires often buy meme coins for no other reason than cultural influence or taxes.

Another altcoin worth mentioning is Chainlink. It sits in a kind of gray zone — not a household name, but essential for data feeds. I’ve seen it appear in several billion-dollar hedge fund filings, usually as a small position. The reason is simple: Chainlink is the leading oracle network, and any serious DeFi play will need it.

To be honest, most top investors treat altcoins like venture capital bets. They put in a tiny fraction of their net worth and expect massive volatility. If you look at public filings for ETFs and corporate treasuries, you’ll see almost zero exposure to altcoins beyond Bitcoin and occasionally Ethereum.

I know a crypto fund manager in Singapore who allocates exactly 1% of his fund to “hedonized” crypto — his term for meme coins and random layer-1s. He laughs and says, “This is my entertainment budget.” That’s a perfect summary of how billionaires view these fliers.

Common Patterns in Billionaire Crypto Portfolios

After reading dozens of interviews, quarterly reports, and on-chain data, I’ve identified five patterns that separate billionaire crypto investors from the rest.

• They Use Carve-outs: Only a small slice of their wealth goes into crypto. Even the most obsessed crypto bull, like Michael Saylor, has a massive software company backing the bet.
• They Buy Bitcoin First: Almost every single billionaire holds Bitcoin or a Bitcoin-related investment product like a trust or ETF. Altcoins come later, and only after Bitcoin.
• They Practice Long-Term Holding: I found almost no evidence that billionaires trade actively. They set up entities that simply accumulate and hold, often in custody with multiple third-party validators.
• They Prioritize Self-Custody: Publicly traded companies have to disclose where assets are held. The trend is clear: coins end up in cold storage, not on exchanges.
• They’re Quiet: The loudest billionaires on social media are usually meme promoters. The serious ones rarely post about crypto. They just buy quietly through their trusts and holding companies.

Let me illustrate this with a table showing the most prominent billionaire crypto investors and their primary holdings, based on public filings and interviews:

Notice that no one on this list has a 50/50 split between Bitcoin and 20 different altcoins. The allocation is heavily tilted towards Bitcoin, with Ethereum a distant second.

How Can Retail Investors Copy Billionaire Crypto Strategies?

You can’t copy their exact wallet size, but you can absolutely copy their discipline. Here’s what I recommend to clients and friends.

Start with Bitcoin dominance. If you’re new, put at least 70% of your crypto allocation into Bitcoin. Only add Ethereum when you’ve understood the technology and the market cycles. That single step automatically eliminates many of the risks that hammer retail investors.

Automate your buys. Set up a recurring purchase on a regulated exchange for Bitcoin and Ethereum. Once a week, buy a small amount. Turn limit orders on so you’re not overpaying. This forces the same layered accumulation that billionaires get from treasury teams.

Never chase a coin because a billionaire tweeted about it. Yesterday it was Solana, today it’s some random layer-1. If it’s not in the top 20 by market cap, most billionaires wouldn’t even look at it.

Diversify the “wrong” way? Actually, billionaires don’t diversify much within crypto. They go heavy on Bitcoin, and then maybe ETH. So don’t over diversify into dozens of coins. That’s a retail mistake. I’ve seen portfolios with 30 coins and almost no Bitcoin — those are usually the people who panic-sold at the bottom.

Consider a self-custody solution. Once your holdings reach a certain level, move them to a hardware wallet. I know that’s inconvenient, but if you want to emulate the people we’re talking about, you need to get comfortable with private keys.
