Ethereum turns eleven on July 30. The best way to mark it is not a list of milestones but an honest answer to the argument you have probably heard at your own kitchen table: that Bitcoin and stablecoins are enough, that ETH is too volatile to be useful, and that staking will never pay as mining did.

Someone on our team recently had this conversation at home. The objection came out fully formed, the way genuinely held opinions do:

“Honestly, I don’t understand why anything besides Bitcoin and stablecoins needs to exist. Ether is too volatile. It’s less convenient. And you’re never going to earn on staking what people earned on proof of work.”

It is a reasonable position held by many people, and it deserves a real answer rather than a defensive one.

SimpleSwap has an unusual vantage point on it. As a swap aggregator, we watch value move all day between exactly the things in that quote: Bitcoin and stablecoins on one side, Ether and its long tail of ERC-20 tokens on the other. He is not a hypothetical to us, but a large and sensible share of the people who swap through SimpleSwap, so the honest thing is to answer him.

Part one: stablecoins are an Ethereum application

Start with the part of the objection that quietly undoes itself.

A stablecoin is a smart contract that moves value by rules a network agrees to enforce, and it works only because someone built a chain where everyone can execute arbitrary rules at once. Bitcoin cannot natively do that, by design: its scripting is deliberately limited, because limitation is the security model. Ethereum made the opposite bet in 2015.

So “Bitcoin and stablecoins are all we need” actually means “digital gold plus one Ethereum-style application is all we need.” A coherent view, but not an argument against programmable chains, because half of it depends on one.

Part two: proof of stake is not a worse deal, it is a different bill

Now the part that sounds strongest and turns out to be backwards. Comparing proof of stake vs proof of work on headline earnings misses what each is paying for.

Proof of work buys security with electricity. The block reward has to cover hardware and energy costs, plus the constant replacement of obsolete machines, so mining revenue looked impressive because most of it was never profit. It reimbursed real-world costs, and those costs set a floor under how much new supply the network had to print.

Proof of stake buys security with locked capital. Validators post ETH as collateral instead of buying rigs, and the protocol takes it if they misbehave. With no electricity bill to reimburse, the same security costs dramatically less in issuance. The Merge in September 2022 cut Ethereum’s energy use by roughly 99.95% and its issuance by close to 88%, and today, around 30% of all ETH is staked across more than 1 million validators.

Here is the part worth sitting with. Ethereum staking yields around 3-4% because the network prints far less. Mining paid more because it printed far more, and that dilution was paid for by everyone holding the asset. A high yield funded by high issuance is not a better deal for a holder. It is the same holder’s pocket, routed through a data centre and converted into heat.

And if you suspect mining was simply better, that hypothesis was tested. Miners forked the chain at the switch to keep proof of work alive, and EthereumPoW still runs as a separate network anyone can hold, with our partners at ELLIPAL keeping a guide to storing ETHW. The verdict since 2022 has been emphatic, but the fact that a fork exists at all is the healthier outcome: in an open ecosystem, the losing side of an argument does not get switched off. It keeps running and ends up being wrong in public.

Proof of stake is not strictly superior, since it concentrates influence differently and favours those with capital to lock. But “you earn less” is not the flaw it sounds like. Earning less because less is printed is the entire point.

Part three: volatility is a property of the asset, not a bug in the network

ETH moves, and it has been through a brutal stretch. But it is not competing with stablecoins for the job of being stable. It is the asset you spend to use the network, and the collateral securing it, that is forfeited by validators who misbehave. A network charging fees in a stablecoin would have to trust that issuer, reintroducing the exact dependency the design exists to avoid.

Bitcoin optimises for being unchangeable. Stablecoins optimise for holding a number still. Ethereum optimises for programmability, and the fuel price floats because demand for the computer floats. You can dislike that without it implying that the computer should not exist.

What eleven years actually bought

The clearest answer to “why does anything else need to exist” is a list of things that could not.

Decentralised exchange. The automated market maker model, where pools are priced by formula rather than by a matching engine, was invented and proven on Ethereum. Every venue now quoting from a pool inherits it.

Layer 2 networks. A second tier of chains inheriting Ethereum’s security while running their own execution, which created its own problem, since value now has to move between networks. Rubic have a good explainer on how a cross-chain swap is assembled.

Identity and naming. ENS made human-readable addresses normal, a decent rebuttal to the convenience complaint on its own. Tangem published a clear primer on how ENS resolves a name to an address.

And underneath it, an engineering record nobody credits enough: Ethereum replaced its own consensus mechanism while running, with billions of dollars on top, without halting the chain or rolling anything back.

Standards are the quietest kind of victory.

There is one more item on that list, and it is the one SimpleSwap knows best.

ERC-20, proposed in 2015, specified almost nothing interesting: how to check a balance, how to transfer, how to approve a spender. It is the least exciting document in crypto, and it is why SimpleSwap can offer 2,800+ swappable assets across 20+ liquidity providers rather than a handful. That long tail is what happens when thousands of teams build against one interface.

“Ethereum’s gift to infrastructure builders was not the chain. It was ERC-20. Before a token standard, adding an asset meant bespoke work every time. After it, supporting the two thousandth token costs almost nothing more than the tenth. Most of what we offer users rests on a specification somebody wrote in 2015, and nobody has ever thrown a party for it.”

Stefan Lauer, Head of Infrastructure, SimpleSwap

That is the small version. The large one is that Ethereum’s most widely adopted invention is not ETH at all. It is the Ethereum Virtual Machine, which became the default other networks chose to be compatible with, because compatibility meant instant access to a decade of tooling and developers who already knew how to build.

It has outgrown its own chain. Neon EVM runs an EVM-compatible layer on Solana, so an app written for Ethereum deploys there without a rewrite. Their team recently walked through the mainnet upgrade changes for Ethereum dApps. As a measure of success: a competing chain’s most direct path to developers ran through speaking Ethereum’s language.

So, are Bitcoin and stablecoins enough?

If your only use for crypto is holding a scarce asset and moving dollars, then honestly, yes. Plenty of sensible people stop there. But the second half of that setup runs on the thing being dismissed. You do not have to own ETH or enjoy its volatility. It is worth noting that the convenient part of your portfolio is built on the invention of the inconvenient part.

And if the argument moves you, the practical step is deliberately unremarkable. You can buy ETH with a card, or swap into it from the Bitcoin and stablecoins you already hold. Making that ordinary is what SimpleSwap spends its time on, and it is the point of the whole eleven years: the interesting engineering ends up buried under something that feels like nothing at all.

If you would rather not think about any of the above, that is fine too. The eleventh birthday present the network would probably appreciate most is somebody using it without noticing it: buy Ethereum, send it somewhere, pay a fee you barely register, and let eleven years of work do their job quietly in the background.

Happy birthday to the world computer. Eleven years, one consensus transplant, no downtime.
