Layer 1 Bets: Why Some Investors Focus on Base Chains
What Is a Layer 1?
A Layer 1 (L1) is a base blockchain. It processes transactions, keeps the main ledger, and provides the rules the network runs on. Ethereum describes itself as a decentralized blockchain network and platform, while its educational materials explain that layer 2s are built on top of layer 1 foundations like Ethereum and Bitcoin.
In simple terms, a layer 1 is the “main road.”
Other projects may build on it, scale it, or depend on it.
Why Some Investors Like Layer 1s
Some investors focus on L1s because they are betting on the growth of the whole ecosystem, not just one app.
If a base chain succeeds, it may benefit from:
More users
More developers
More transactions
More apps built on top of it
Ethereum, for example, is described as home to thousands of cryptocurrencies and applications across areas like DeFi, NFTs, gaming, social, and stablecoins.
That means an L1 can sometimes feel like a broader bet on network activity, rather than a narrower bet on one product.
The “Picks and Shovels” Idea
Some investors view base chains as a kind of infrastructure play.
The logic is:
Apps may come and go
Narratives may rotate
But strong base infrastructure can remain useful across multiple cycles
This is similar to owning the road instead of guessing which single car will win.
That does not mean layer 1s are safe.
It just means some investors prefer owning a platform that many other projects depend on.
Security, Data, and Ecosystem Effects
Layer 1s matter because they often provide the core security and data layer for activity built above them. Ethereum’s layer 2 documentation explains that Ethereum acts as a data availability layer for its L2 ecosystem, and Base’s documentation says a Base transaction includes both an L2 execution fee and an L1 security fee tied to publishing transaction data back to the underlying layer 1.
That helps explain why some investors think base chains can capture lasting value:
They sit under a large share of activity
They may benefit as more networks and apps rely on them
They can become central pieces of an ecosystem
The Risks of Layer 1 Bets
Layer 1 investing still comes with major risks.
A base chain can struggle if:
Developer activity slows
Users move to competing ecosystems
Fees stay too high
Scaling or governance problems hurt adoption
Even within the Ethereum ecosystem, the rise of L2s reflects the idea that base layers can be secure and important while still needing help with cost and scale. Ethereum’s educational materials describe L2s as a response to those scaling limits.
So a layer 1 is not automatically the “best” place to invest.
It is just one kind of crypto bet, with its own strengths and weaknesses.
Takeaway
Some investors focus on layer 1s because base chains are the foundation other apps and networks build on. The appeal is that if the ecosystem grows, the base layer may benefit from that broader activity. But layer 1s still face competition, scaling pressure, and adoption risk. As a beginner, it helps to see an L1 not as a guaranteed winner, but as a bet on the strength and staying power of a blockchain ecosystem.
