Bitcoin Cash price moved back above USD 289 on November 6 as the network's developers continued reviewing a proposal aimed at improving long-term signature security. Investing.com displayed BCH at USD 289.12 at 18:45:55 Berlin time, with a daily range of USD 275.49 to USD 293.30. Against the verified November 5 UTC close of USD 271.90 reported by Mercatus Data, the move represented a 6.33 percent gain.

The price reading remains a point-in-time observation rather than a closing price. Investing.com also listed a market capitalization of USD 5.83 billion, 24-hour volume of USD 245.85 million and a circulating supply of 20.11 million BCH. The page ranked Bitcoin Cash 18th among cryptocurrencies at the time it was checked.

Quantum-security proposal under review

The most relevant recent project development is CHIP-2026-06, a Cash Improvement Proposal for post-quantum and hybrid signatures. The Quantum Insider reported on November 5 that the proposal remains under discussion and implementation review, with potential lock-in on November 15, 2026, and mainnet activation targeted for May 15, 2027.

The proposal would introduce the OP_SIGHASH opcode to expose transaction data already calculated during signature verification. Its hybrid design is intended to require both classical and post-quantum checks, while preserving existing address formats and wallet compatibility. The proposal is therefore a development-stage infrastructure initiative, not an activated network change.

Market context remains volatile

Bitcoin Cash price data had been under pressure earlier on November 6. CryptoTicker reported a morning reading near USD 264 and attributed the decline to a broad crypto-market sell-off rather than a Bitcoin Cash-specific project trigger. The same analysis placed the 100-day moving average near USD 261 and the 200-day average near USD 280.

For investors, those levels provide context rather than a forecast. BCH's move above the November 5 UTC close does not establish that the signature proposal caused the price change. The asset remains sensitive to wider crypto liquidity and leverage conditions, while the CHIP's November review deadline may provide a separate event for developers and network participants to monitor.
