A what‑if from the future

What if a pre-halving hashrate grab crushes miner margins?

A pre-halving hashrate land-grab squeezes public miner margins first (MARA, RIOT, CLSK), with forced miner BTC sales capping spot and dragging MSTR as the levered proxy. Rhymes with the 2021 China hashrate ban and post-2024-halving margin compression, which crushed miner equities far more than BTC itself. Forward angle: rising AI-datacenter competition for power makes the energy-cost spike sharper than prior cycles.

What it would mean

If this plays out, it is a mixed shock. Anticipation of the 2028 halving triggers a hashrate land-grab, spiking energy costs and squeezing public miner margins. The trigger decomposes into signed root‑shocks — Bitcoin ▼ · Crypto confidence ▼ — which propagate through our causal graph to the markets below.
