Everything copied, one thing missing
The 2017 fork gave BCH the whole supply design: the 21 million cap, the halving cadence, proof-of-work issuance. If supply mechanics were what priced Bitcoin, the two coins would have converged. They did the opposite — which is the cleanest evidence in the map that the scarce-supply story prices nothing by itself. Demand is the variable, and demand did not fork.
Security follows price, not the reverse
Hashrate goes where the block reward is worth most, so BCH runs on a small fraction of the SHA-256 fleet that secures Bitcoin. That is not a detail: a minority-hashrate chain borrows its security margin from the majority chain’s idle capacity, and the discount the market applies to that arrangement is structural, not sentimental.
The halving, without the audience
BCH halves on roughly the same schedule as Bitcoin, but a halving is a supply event — and supply events matter in proportion to the demand pressing against them. The same event that anchors a year of Bitcoin narrative passes here as a calendar line. If you trade it, trade the relative pair, not the event.
Reading it
No options book, so the read is funding, open interest and the cost to trade — and BCH mostly trades as a high-beta echo of Bitcoin’s regime. When it decouples, the move is usually flow finding a thin book, the shape described in thin pools and volatility.
