What it actually costs to sell ETH
Selling $100,000 of ETH into each exchange’s resting bids, measured against the mid price:
| Exchange | Lost | Got back | Measured |
|---|---|---|---|
| Coinbase ETH/USD | 0.01% | $99,986 | 2026-10-08 |
| Kraken ETH/USD | 0.02% | $99,983 | 2026-10-08 median of 37 |
Exchange figures need an account there (and KYC, a permitted country, the tokens already deposited), are before trading fees, and are never averaged with the on-chain figure. Binance is not included: it refuses requests from the region our servers are in. How this is measured →
Watch this number instead of remembering it. A free account keeps ETH on a list, records where it stood the day you added it, and emails you if selling it on these exchanges gets materially harder — one message, not a series. The measurement itself stays public; the account is for being told when it moves without you looking.

What we’ve written about ETH
-
What a blockchain actually guarantees — and what it does not
· 3 min
Being on a blockchain proves the ledger was not tampered with. It proves nothing about the project, the team, or whether you will be able to sell. -
Why a crypto payment cannot be undone
· 3 min
Card payments can be reversed by someone other than you. Crypto payments cannot. That single difference explains most of the rules, and most of the losses. -
Can you actually sell it? A short guide to liquidity

The difference between what a holding is worth on paper and what you would receive for it — slippage, depth, sell restrictions, and how to check before you buy.
What Ethereum is
Ethereum is a programmable blockchain launched in 2015 by Vitalik Buterin and a group of co-founders. Where Bitcoin tracks who owns what, Ethereum runs code: smart contracts that execute exactly as written, which is what most stablecoins, lending protocols and NFTs are actually built on.
Every action costs a fee paid in ETH, called gas, which compensates the network for the computation. In 2022 Ethereum replaced mining with proof of stake, cutting its energy use by well over 99% and allowing holders to stake ETH to help secure the network and earn a yield.
The honest limitations are real. Fees rise sharply when the network is busy, which pushed most activity onto layer-2 rollups and left the user experience fragmented across chains. Smart contracts are only as good as their code, and billions have been lost to bugs and exploits. Staking rewards are not risk-free income — they are payment for taking on real technical and market risk.
What Ethereum can do
Selling $100,000 on Coinbase lost 0.01% against the mid price, before trading fees. Check your own amount →
Our own measurement · measured 8 October 2026
Ether sits at an address controlled by a key. In a wallet you run yourself, the wallet's maker never has custody of the funds, and the recovery phrase is the only way back in. What a wallet actually is →

Anyone can send ether to any address. A block arrives every 12 seconds, and the fee is paid in ether and rises when the network is busy. Why a payment cannot be undone →

Ethereum pays ether to those who stake it. Staking on your own takes at least 32 ETH and a machine that stays online, and a validator that breaks the rules loses part of its stake. With less, you stake through a pool or an exchange, and then you depend on them.

This is what Ethereum was built for: programs stored on the chain that run exactly as written. Each app is its own code with its own flaws, and code that is wrong stays wrong.

Ether has no maximum. New ether is paid to stakers and part of every fee is destroyed, so the total can rise or fall.

Ether reaches the networks built on Ethereum, such as Arbitrum, through a bridge, and other chains as a wrapped token. Either way it depends on the bridge's code and on whoever runs it.

About the asset
Ethereum has no token contract — it is the native asset of its own chain, not a token issued on someone else's.
