3 Reasons Bitcoin Will Always Outshine Other Blockchains — Cathie Wood Explains

• Cathie Wood says Bitcoin’s fixed supply, unmatched security, and first-mover advantage make it the foundation of global digital finance.

• While Ethereum powers the DeFi ecosystem, Wood believes Bitcoin will always remain the dominant and most valuable blockchain.

Cathie Wood, Founder and CEO of ARK Invest, has once again reaffirmed her long-term conviction in Bitcoin,  calling it the world’s most powerful and enduring digital asset. Speaking in a recent interview The Master Investor Podcast with Wilfred Frost, Wood outlined why Bitcoin will continue continues to dominate the crypto space. She believes no other blockchain will surpass it in scale or significance.

Wood began by distinguishing between cryptocurrencies and crypto assets, emphasizing that Bitcoin “owns the cryptocurrency space.” She explained that while stablecoins such as USDT and USDC also fall under the cryptocurrency category, they are primarily pegged to the U.S. dollar and collateralized by Treasury securities.

“Bitcoin will continue to be the biggest asset by far,” Wood said, noting that its strength lies in its rule-based monetary system. “There are only 21 million units,  that’s where it stops. We’re already at about 20 million,” she added, referring to the amount of tokens in supply and the already circulating. This predictable scarcity, she said, forms the foundation of Bitcoin’s value as a global monetary system built on transparent and immutable rules.

Wood also discussed how stablecoins are finding utility in decentralized finance (DeFi). She pointed to Coinbase’s USDC product, which allows holders to earn yields by deploying their coins in DeFi ecosystems.

Cathie also gave  3 reasons why Bitcoin will remain superior to Ethereum.

1. Bitcoin Is the Global Monetary System

Wood’s first point was clear: Bitcoin is not merely an investment but a global monetary network governed by mathematical rules, not human discretion. “This alone,” she said, “is a very big idea.” By limiting supply and adapting blockchain technology, Bitcoin is transparent. It cannot be manipulated by central banks or governments.

2. Bitcoin Is the Most Secure Layer-1 Technology

The second reason, according to Wood, is that Bitcoin is also a technology, a Layer 1 protocol that has never been hacked. This makes it more reliable compared to other blockchains. “This is why the monetary system is based on Bitcoin,” Wood noted, highlighting how its resilience has made it the ultimate store of value in the digital era.

3. Bitcoin Is the Pioneer of a New Asset Class

Finally, Wood described Bitcoin as the pioneer of an entirely new asset class. “It was the first of its kind,” she said, recalling how ARK Invest wrote its first whitepaper on Bitcoin back in 2016. That early recognition, she added, stemmed from the realization that Bitcoin was not just another digital experiment 

Why Bitcoin is Always Going to be Bigger Than Ethereum

While Wood maintains that Bitcoin will always be the largest and most dominant asset, she did not dismiss Ethereum’s importance. She acknowledged that Ethereum “plays a very important role in the DeFi ecosystem,” especially as more activity migrates to Layer 2 solutions.

She cited Robinhood’s plan to launch its own Layer 2, following Coinbase’s introduction of “Base.” However, she expressed concern that too many Layer 2 networks could start competing against one another, potentially consolidating back into Layer 1 over time. “That’s why we’re invested in Ether,” she said, describing it as the engine that powers the DeFi world.
