The Ethereum split and the 2026 ETC price divergence

The 2016 DAO Vulnerability

The DAO hack split Ethereum. In 2016, the project raised $150 million in ETH from over 11,000 participants. Christoph Jentzsch released the open source code for the organization. The token sale lasted 28 days. The smart contract code contained a re-entrancy bug. An attacker exploited this flaw on June 17, 2016, to siphon 3.6 million ETH. This theft equaled $60 million at the time. The DAO contracts contained 14% of all ether in circulation. The community debated the moral choice between immutability and fund recovery. Most stakeholders supported a hard fork to return funds to investors. Block 192,000 saw the implementation of the hard fork on July 20, 2016. One group refused the change and kept the original history, which became Ethereum Classic. I call this the defining moment of the network.

The split was permanent.

Developers like Vitalik Buterin proposed a soft fork first to blacklist the attacker, but the attacker threatened to bribe miners with 1 million ETH and 100 bitcoin. The attacker moved the stolen funds into a "child DAO" with a 28-day withdrawal lock. The community eventually chose a hard fork to roll back history and reallocate funds to a different smart contract. This decision changed the blockchain. The SEC concluded in 2017 that DAO tokens were securities.

Ethereum Classic maintains a fixed supply of 230 million tokens. This chain prioritizes "code is law" over the flexibility seen in the main Ethereum network.

The 2026 Mining Squeeze

The July 2026 fifthening hit hard. On July 22, 2026, the network reduced block rewards to 1.6384 ETC per block. This drop from 2.048 follows the 5M20 issuance schedule. It happened at block 25,000,001.

The September $18 hash rate collapse ruined many miners. This sudden drop follows the summer trend where high electricity costs force miners to scale back. I see the same pattern.

Miners using GPUs or older hardware struggle to maintain profit after the reward cut. Efficient ETCHash ASICs remain the only way to stay profitable if power costs stay below $0.10 per kWh. Most home setups using retail electricity lose money because margins are thin. The January 5, 2026, 51 percent attack showed how small networks face risks when hash power shifts. That attack lasted three days and caused $1.1 million in losses according to SlowMist. Coinbase suspended ETC trades to protect users during the reorganization. Gate.io corroborated these findings and reported losses of $40,000. The attacker used deep chain reorganization to execute double spends while Bitrue reported a double spend worth $14,000. The attacker in January 2026 acquired over 50 percent of the network’s hashrate.

The current price is low.

The Resulting Divergence

The price diverged. While the network remains secure due to the proof of work mechanism, the dwindling block rewards and the recent collapse in hash rate create a massive gap between computational effort and market value.

The current ETC price is low compared to its 2021 high of $176. In 2024, the price sat near $29.70 before this recent downturn. This price drop makes the reward cut feel heavier. You should watch the hardware efficiency closely.

Is the mining industry dead?
