Bitcoin Cash jumped 16.7% as a disputed network upgrade approached

Bitcoin Cash rose sharply on November 4, 2018 as an approaching network upgrade—and the possibility that incompatible node software could divide the chain—moved into the market’s immediate focus.

CoinMarketCap’s historical snapshot listed BCH at $560.18, up 16.72% over its trailing 24-hour measurement and 27.74% over seven days. The aggregator ranked Bitcoin Cash fourth among tracked crypto assets, with a reported market capitalization of $9.77 billion, circulating supply of 17,440,500 BCH and trailing 24-hour volume of $1.45 billion.

The move stood out in a broadly positive but much quieter session. The same snapshot showed bitcoin up 0.28% over 24 hours at $6,376.13, ether up 3.66% at $207.49 and XRP up 1.59% at $0.4627. Those comparisons establish BCH’s relative outperformance within CoinMarketCap’s dataset; they do not prove why individual traders bought it.

A scheduled upgrade with incompatible choices

Bitcoin ABC had announced version 0.18.0 on August 20. Its rules were scheduled to activate when the median timestamp of the preceding 11 blocks reached Unix time 1542300000 on November 15. The published specification included canonical transaction ordering, two new data-signature opcodes, a minimum transaction size and tighter script-validation rules.

Canonical transaction ordering would require transactions, apart from the coinbase transaction, to be arranged by transaction identifier inside each block. Bitcoin ABC described that change as groundwork for future scaling. The new OP_CHECKDATASIG and OP_CHECKDATASIGVERIFY operations would allow scripts to validate messages originating outside the blockchain, potentially supporting oracle and cross-chain applications.

The upgrade was not supported by every significant participant. In August, nChain announced Bitcoin SV as an alternative full-node implementation developed at the request of CoinGeek and other miners. Its announcement explicitly opposed changes it considered unnecessary and presented the software as a choice for miners seeking a different protocol direction.

By November 4, the existence of competing implementations made a chain split a credible risk, but not an accomplished fact. Miner behavior, software adoption and service-provider policies after activation remained unknown. It would therefore have been premature to describe two durable successor assets or assign either proposal the future BCH identity.

Exchange support became part of the trade

Contemporaneous Cointelegraph reporting connected the rally’s timing with Binance’s November 2 announcement that it would support the approaching hard fork. The exchange reportedly planned to suspend BCH deposits and withdrawals on November 15 so deposits could be fully processed before activation.

That operational support mattered because custodial exchanges had to decide how to handle balances if incompatible chains survived. A pre-fork BCH balance could potentially correspond to assets on both ledgers, but access would depend on each venue’s snapshot, wallet, replay-protection and listing policies. An exchange saying it would support a fork did not establish which chain would prevail, guarantee two freely tradable assets or eliminate technical risk.

The market evidence supports a narrower interpretation: traders assigned materially more value and activity to BCH as the upgrade approached. It does not isolate Binance’s notice, the prospect of additional forked coins, protocol preferences or broader market momentum as the rally’s sole cause.

What the November 4 record established

The defensible event-day conclusion was that BCH had become the clear large-cap market outlier while competing upgrade plans raised the stakes of the November 15 activation. CoinMarketCap’s figures were aggregated snapshot values rather than a universal close, an executable price on every venue or a complete order-book record. The eventual chain outcome and post-fork prices were still unknowable on November 4 and are not used to interpret the session.
