Almost nobody starts in crypto with a neutral question. It’s usually Bitcoin vs Ethereum, asked at an exchange withdrawal screen, and the two names you half recognize sit there with nothing obvious to separate them. Both move money with no bank in the middle, both sit on a public blockchain, and both will take anyone who turns up.
Ethereum’s own documentation doesn’t dress it up. That, it says, is where the similarities end.
So here’s our short answer. Bitcoin if you want a hard limit on the number of coins, a ledger with one job, and something you’ll sit on for years. Ethereum if you’re after apps, stablecoins and staking rewards, and you don’t mind picking up how layer 2 networks behave.
What follows: what each network is, who’s guarding it, what a transfer costs you, how long you’re kept waiting, and which wallets now hold the pair. Every figure comes out of Bitcoin’s or Ethereum’s own docs or source code, and we say which.

What Bitcoin actually is
In its own words, Bitcoin is a consensus network that enables a new payment system and a completely digital money. A cryptography mailing list got the first specification and proof of concept from Satoshi Nakamoto back in 2009.
Dig into the genesis block and you’ll find the Unix timestamp 1231006505, which works out to January 3, 2009, plus a coinbase message lifting a Times headline about a second bailout for the banks. We still think that’s the best joke anyone has buried in software.
Proof of work does the guarding. Miners burn electricity racing through a calculation, and whoever wins gets to append the next block. That same race explains why so little else was ever bolted on: one ledger, one asset, and a scripting language that barely stretches past moving coins under conditions.
For most holders, that shortage of features is the feature. Fewer parts means fewer things to misread and fewer ways to lose money by tapping the wrong button. Walking through it once helps, and our guide to sending Bitcoin to another wallet covers the whole flow.
The parts of Bitcoin that matter
- There will never be more than 21 million bitcoins, and Bitcoin Core’s consensus code pins MAX_MONEY at 21,000,000 BTC.
- Miners collected 50 BTC per block at the start, and that subsidy gets cut in half every 210,000 blocks, which the source comment reckons at approximately every 4 years.
- Blocks show up about every 10 minutes on average, and difficulty is retargeted once every 2,016 blocks, so about once every two weeks.
- The old rule capped a block at 1,000,000 bytes. SegWit swapped it for a block weight limit of 4,000,000 and switched on at height 481,824.
- Since block 709632, Taproot has been live, bringing Schnorr signatures and Merkle branches in the name of privacy, efficiency and flexibility.
What Ethereum actually is
Ethereum bills itself as a decentralized blockchain network and software development platform running on the cryptocurrency ether. Vitalik Buterin floated the idea in a white paper in 2013, gathered a handful of co-founders, and the thing went live in July 2015.
Their own one-liner for the split is hard to improve on. Bitcoin is a tool for sending value; Ethereum is a platform for building it.
Smart contracts are why. Each one is a program parked at an address on the chain, anybody at all can deploy one, and by default nobody gets to delete it afterwards.
Making the base chain cheap was never the plan. Low fees were handed to layer 2 networks, a layer 2 being a separate chain that bundles transactions together and posts the data back down to Ethereum. We’ve spent time in that neighborhood already, in Arbitrum vs Optimism and in our roundup of ZK roll-up projects.
The parts of Ethereum that matter
- The clock runs in slots of 12 seconds, 32 of them to an epoch, with a block expected in each slot.
- Gas measures computational work, and the base fee the protocol sets can shift by no more than 12.5% from one block to the next before it’s burned instead of handed to a validator.
- Your own validator wants 32 ETH; a pool will take 0.01 ETH; one validator tops out at 2048 ETH.
- Nobody owns the software. Geth, Nethermind, Besu, Erigon and Reth all handle the execution side.
- Upgrades keep arriving. PeerDAS came with Fusaka on December 3, 2025, and Glamsterdam is penciled in for Q4 2026.
Bitcoin vs Ethereum on security
Attacking either chain costs a fortune. What differs is the currency the attacker pays in: power bills and silicon on one side, staked ETH on the other.
Bitcoin’s whole defense is that mining race. Machines grind through mathematical calculations to confirm transactions and increase security, and the winner walks off with the block reward. Beyond wasted work, though, the protocol has no way to punish a miner who misbehaves.
Validators on Ethereum can be hit where it hurts, and the name for it is slashing. Get slashed alone and you might drop under 0.1% of your stake; take part in something coordinated and the penalty runs to 100% of the validator’s stake getting destroyed. Rolling back a finalized block would mean an attacker signing away at least a third of all staked ETH.
There’s a second tool for a chain that seizes up. Whenever finalization fails for more than four epochs the inactivity leak kicks in, bleeding away the staked ETH from validators voting against the majority. Nothing like it exists on Bitcoin, for the simple reason that no stake is sitting there to confiscate.
Client diversity deserves a line too. Ethereum’s documentation makes the case plainly, that multiple client implementations make the network stronger by reducing its dependency on a single codebase, and it has several of them across execution and consensus. Bitcoin, at release 31.1 of Bitcoin Core, runs on one implementation that practically everyone uses, which bothers us more than it seems to bother the market.
Here’s the threat that empties real wallets, though, and it isn’t either protocol. Once a Bitcoin transaction is confirmed it can’t be undone, and a contract interaction on Ethereum is no different. Choose the wrong network or paste the wrong address and the money’s gone, with nobody on earth able to claw it back.
Look at the network selector twice on every send. When the string in your clipboard means nothing to you, read our explainer on what a wallet address is before you go further.
Living with Bitcoin vs Ethereum day to day
The addresses give it away first. Bitcoin’s native SegWit strings open with bc1q, Taproot ones with bc1p, while Ethereum hands you 42 characters, 40 hex digits sitting behind a 0x.
Bitcoin simply asks less of you, and that counts for more than it sounds like. A single asset, a single network, a single screen to read. Ethereum wants you to know about gas, token standards, and which of several layer 2 networks you happen to be sitting on right now.
On wallets, the gap has closed. MetaMask switched on Bitcoin on December 15, 2025, and its own announcement promises you can buy, swap, trade, bridge and send Bitcoin directly, with no wrapped BTC needed. For now that’s the native SegWit derivation path, with Taproot still to come.
Hardware covers the pair as well. Ledger takes Bitcoin on the Stax, Flex, Nano Gen5 and the Nano classics through the Ledger Wallet app, keeping private keys offline on a certified Secure Element chip, and Ethereum staking runs out of that same app. Trezor’s coin list gives Bitcoin send, receive, buy, sell and swap on every model, and throws staking in for Ethereum.
Picking the device is a separate argument. We’d open with our Ledger vs Trezor comparison, then our ranking of the best Bitcoin hardware wallets.
Bitcoin vs Ethereum: what you pay and how long you wait
Size is what Bitcoin bills you for. Fees vary over time with demand for space in the blockchain, and the fee is relative to the number of bytes in the transaction. No dollar average appears anywhere on bitcoin.org, so any number you read elsewhere is a snapshot of one particular afternoon.
Computation is what Ethereum bills you for. Shifting ETH from one account to another burns 21,000 units of gas, and your total comes out as gas used times base fee plus priority fee. The protocol picks that base fee, it moves by 12.5% per block at most, and it gets burned rather than paid out to anybody.
Helpfully, the Ethereum docs run the sums themselves. Put a 10 gwei base fee with a 2 gwei tip against 21,000 gas and you’re out 0.000252 ETH, of which the validator pockets 0.000042 ETH while 0.00021 ETH vanishes. A gwei, for reference, is one-billionth of an ETH.
Converted to money, ethereum.org puts the mainnet average at about $0.025 at the time of writing (September 2026), with roughly $0.0011 across the Ethereum-backed layer 2 networks. Neither one holds still, since both track the gas market, so treat them as approximate.
| What’s keeping you waiting | Bitcoin | Ethereum |
|---|---|---|
| The next block | Roughly 10 minutes on average | One every 12 seconds |
| Your first confirmation | Anywhere from 10 to 60 minutes | A single 12-second slot |
| Settlement you’d bet on | 6 confirmations, so about an hour | Around 15 minutes to finalize |
| Where the fee comes from | Byte count, priced by demand for block space | Gas spent, times base fee plus tip |
| Approximate fee (Sept 2026) | Nothing official published in dollars | Roughly $0.025 on mainnet, roughly $0.0011 on a layer 2 |
Both projects shove ordinary traffic down to a cheaper floor. Bitcoin’s is the Lightning Network, where two people open a payment channel and settle off chain, which the project reckons allows exceptionally low fees and payments in milliseconds to seconds. Ethereum’s floor is rollups, and ethereum.org lists Base, Arbitrum One, Linea, Scroll and Optimism among them.
What your Bitcoin or Ethereum pays back
Sitting on either coin is free. The split appears the moment you ask the network to pay you something, or decide you’d rather check the chain yourself than trust a stranger’s server.
Bitcoin pays nothing from the protocol. Fresh coins go to miners, and mining is an electricity and hardware trade, not a toggle inside your wallet. Whenever somebody offers you a yield on BTC, a company is taking custody of those coins, and that’s a wholly different risk.
Stakers on Ethereum do get paid. Going solo means at least 32 ETH to activate your own validator, pooled and liquid services accept as little as 0.01 ETH, and a single validator can hold up to 2048 ETH. As we write, 43,162,677 ETH is staked, 35% of supply, earning an APR of 2.5%.
Not everyone wants a machine humming in a cupboard. Our rundown of the best crypto staking platforms covers the alternatives, with the caveat we always repeat: pass your coins to a platform and your self-custody is over.
Checking the chain yourself is dramatically cheaper on Bitcoin. What bitcoin.org asks for is 7 gigabytes of free disk space, 2 gigabytes of RAM, upload speeds of at least 400 kilobits per second and 6 hours a day of uptime, along with about 740 gigabytes of download on that first startup. Over on Ethereum, Erigon will sync a full archive node using around 2TB of disk space in under 3 days.
That difference reaches past the spec sheet. Affordable nodes mean more people checking the rules without asking permission, which is the entire point of holding your own coins.
Power is the last running cost, and it’s a rout. Post-Merge, Ethereum draws approximately 0.0026 TWh a year, down by more than 99.988% on its proof of work era. Bitcoin sits at 149 TWh a year in the same ethereum.org table, a figure credited to the Cambridge Bitcoin Electricity Consumption Index.
What we like, and what we don’t
Bitcoin, the honest tally
Ethereum, the honest tally
So which one belongs in your wallet?
Putting money away for years and want the plainest asset going? Bitcoin. That 21 million ceiling lives in the consensus code, the ledger has exactly one job, and a node that verifies the lot runs on a laptop you’d otherwise throw out.
Want the balance working while you hold it? Ethereum. Staking returns 2.5% APR as we write, contracts run the apps and stablecoins people genuinely use, and a layer 2 transaction averages about $0.0011.
Moving small sums constantly? Study the second layers before you commit to a chain. Lightning closes Bitcoin payments in milliseconds to seconds, and rollups like Base and Arbitrum One charge you fractions of a cent.
Bitcoin vs Ethereum: your questions
Is Bitcoin or Ethereum faster?
Ethereum, if you mean getting into a block. A block turns up every 12 seconds on Ethereum, against roughly 10 minutes on average for Bitcoin. On full settlement the two move closer together, with Ethereum finalizing in about 15 minutes and most Bitcoin users sitting through 6 confirmations.
Which one is cheaper to use?
Ethereum, as long as you stay on a layer 2. The averages ethereum.org publishes are about $0.025 for mainnet and about $0.0011 for Ethereum-backed layer 2 networks. Bitcoin gives no dollar average of its own, because the fee is priced per byte and rises with demand for block space.
Will there really only ever be 21 million bitcoins?
Yes. bitcoin.org says only 21 million bitcoins will ever be created, and Bitcoin Core’s consensus code backs it up by pinning MAX_MONEY at 21,000,000 BTC. Miners started on 50 BTC a block, and that halves every 210,000 blocks, which works out at roughly four years.
Does Ethereum cap its supply?
No, and it never has. Validators receive new ETH at a rate the protocol limits, while part of every transaction fee is permanently burned. ethereum.org calls the outcome alternating periods of inflation and deflation, driven by how busy the network happens to be.
Can a single wallet hold both BTC and ETH?
It can. MetaMask brought Bitcoin aboard on December 15, 2025, next to Ethereum, Solana, Monad and Sei. Ledger runs both chains from the Ledger Wallet app, and Trezor handles the pair on all of its models.
Is there any way to stake Bitcoin like ETH?
Not at the protocol level. Bitcoin’s new coins are paid to miners, who spend electricity and hardware to earn them, so there’s nothing to stake. Ethereum is paying stakers 2.5% APR as we write, starting at 32 ETH for your own validator or 0.01 ETH inside a pool.
What if I send BTC to an Ethereum address by mistake?
You’ve lost it. The formats differ between the chains, a confirmed Bitcoin transaction can never be undone, and nobody can reverse an Ethereum transaction either. Read the network selector in your wallet before every single send.
Our verdict: Bitcoin or Ethereum?
Treat it as savings and Bitcoin wins. Its 21 million ceiling is written into the consensus code, the network hasn’t missed a beat since January 3, 2009, and you can audit the entire chain on kit already sitting in your house. What you hand over for that is a 10-minute block and a scripting language that does next to nothing.
Judge it as somewhere to do things and Ethereum wins. Blocks arrive every 12 seconds, staking returns 2.5% APR, and layer 2 transactions average about $0.0011. The bill this time is complexity, roughly 15 minutes before anything is final, and a supply that has no ceiling at all.
Plenty of people we know hold both, and honestly that looks like the sensible answer. A single wallet now spans the two chains, so the decision is per transaction and not for life.
