Volume Bubbles Chart (1h)
Each 1-hour candle's volume is signed by its direction (up candles count as net buying, down candles as net selling) and drawn as a bubble at the closing price, green for buying and red for selling. Bubble size and colour intensity show how strong that flow is compared with the last 300 candles: the strongest 30% get full bubbles with their USD value, the rest stay as small dots. Unusually large bubbles flag aggressive buying or selling worth a closer look, often near breakouts, reversals or key levels.Seasonal Chart
Plots one line per calendar year showing the % change since the start of that year, with the current year highlighted against up to four previous years. Lining the years up on the same calendar shows whether the price tends to rise or fall in the same months, helping you spot recurring seasonal patterns. Treat it as context rather than a forecast: past seasonality does not guarantee future moves.Ethereum Classic Markets
Ethereum Classic Historical Data
About Ethereum Classic (ETC)
Ethereum Classic (ETC) is the original Ethereum blockchain, kept alive by people who refused to reverse a 2016 hack. It runs smart contracts in much the same way as Ethereum, but miners using proof-of-work still secure it. ETC is the coin that pays transaction fees and rewards those miners. Prices on this page come from FMchart's composite index of ETC trading on several exchanges, shown in US dollars.
The DAO hack and the 2016 split
The DAO was a large smart contract that had raised about $150 million. In June 2016, an attacker used a bug in it to drain millions of ether. In July 2016, the Ethereum Foundation backed a hard fork that returned the funds to their owners. Part of the community rejected that change. They kept running the unchanged chain, which became Ethereum Classic. Supporters sum up their view as 'code is law': contracts should run exactly as written, even when the result is painful.
Mining with Etchash
Because ETC uses proof-of-work, miners compete to add each block with graphics cards and other hardware. The Thanos upgrade (ECIP-1099), activated in November 2020, changed the mining algorithm to a variant called Etchash. It shrank the large data file miners must hold in memory, so GPUs with 4 GB of memory could keep mining for longer. The upgrade came three months after three 51% attacks in August 2020, when attackers rewrote thousands of blocks.
Rewards that shrink by a fifth
Ethereum Classic follows a fixed monetary policy set out in ECIP-1017, often called 5M20. The chain is divided into eras of 5 million blocks. The block reward was 5 ETC in the first era and drops by 20% at the start of each new era. Each era therefore creates fewer coins than the one before. Under this schedule, total supply can never exceed about 210.7 million ETC.
Olympia: a proposed network treasury
A package of proposals called Olympia, ECIPs 1111 to 1119, would bring Ethereum's EIP-1559 fee market to ETC. Instead of burning the base fee, ECIP-1111 would redirect it to an on-chain treasury governed by smart contracts. Supporters argue that ETC lacks steady funding for core development and infrastructure. A competing proposal, ECIP-1116, would instead pay most base fees to miners, and none of these changes has been activated. Olympia takes effect only if node operators and miners adopt it.
Hashrate, rivals and upgrade politics
A proof-of-work chain is only as safe as the mining power behind it. When that power is modest, an attacker can gather enough to overpower honest miners, which is what happened in 2020. ETC also competes with Ethereum and many other smart-contract networks for users and developers. Upgrades need broad agreement among miners, node operators and developers, and debates such as Olympia can take a long time to settle.

Ethereum Classic (ETC) FAQ
What is Ethereum Classic (ETC)?
Ethereum Classic is the original Ethereum chain that carried on after the 2016 DAO fork. It runs smart contracts, is secured by proof-of-work mining and uses ETC to pay fees and reward miners. Under the ECIP-1017 schedule, supply can never go above about 210.7 million coins.
What is the difference between Ethereum and Ethereum Classic?
The two chains share the same history up to July 2016. Ethereum then adopted a hard fork that reversed The DAO hack, while Ethereum Classic kept the unchanged ledger. Since then they have been separate networks with separate coins and upgrade paths. ETC keeps proof-of-work mining and a reward schedule that shrinks over time.
Is Ethereum Classic still mined?
Yes, ETC is still a proof-of-work coin secured by miners. They run Etchash, adopted in the November 2020 Thanos upgrade. It slowed the growth of the data file miners must hold, so 4 GB cards could keep mining for longer. Block rewards fall by 20% every 5 million blocks, so mining income in ETC terms keeps shrinking.
How much is Ethereum Classic worth today?
One ETC is worth about $7.5293 in FMchart's composite feed. Over the last day, trading in ETC came to roughly $3.43M across the exchanges in FMchart's composite. Because the figure pools several venues, it can sit a few cents away from the quote on any one platform.
How many ETC coins exist, and what is the supply cap?
About 158,829,174 ETC exist today, and the ECIP-1017 schedule caps the total at roughly 210.7 million. Multiplied by the current price, that is a market capitalization near $1.20B, rank 70 among cryptocurrencies. Miners still receive new coins, though each 5-million-block era pays a fifth less.
When did ETC reach its record high?
ETC's peak price was $167.09, reached on May 6, 2021 according to market data. Since then the coin has traded far lower for years at a time, so that record describes the past, not the future. Today's percentage gap from the high, and from the all-time low, sits in the Price Statistics panel.
How has Ethereum Classic done month by month?
In FMchart's composite price history (since August 2018), ETC gained the most in April 2021 (+157.7%) and fell the hardest in April 2022 (-45.5%). Every other month is in the Monthly Returns (USD) grid, and quarter-end closes sit in the Quarterly Closing Price (USD) table. Gains and losses have come in uneven bursts, which makes them a poor basis for forecasts.
What was the Ethereum Classic 51% attack?
In August 2020, attackers gathered enough mining power to rewrite ETC's recent history three separate times. The largest attack, on 29 August, reorganized more than 7,000 blocks, roughly two days of mining. The episode showed how exposed smaller proof-of-work chains can be, and the Thanos mining upgrade followed in November 2020.
Is Ethereum Classic a good investment?
FMchart cannot answer that for you, since it does not offer investment advice. ETC has a capped supply and a long record. It also has a history of 51% attacks, many competing smart-contract chains and an unsettled funding plan. Its price has swung widely over the years, in both directions.
What moves the price of ETC?
ETC usually follows the wider crypto market. Coin-specific drivers include mining economics, since each 20% reward cut changes miner income, and news about network security. Progress or delays on proposals such as Olympia, exchange listings and interest in proof-of-work smart-contract platforms can also shift demand for ETC.
