Xu hướng lợi nhuận ASIC — 90 ngày qua

For every rig in the ASIC class we compare the average revenue over the last 24 hours against the average over a 2-day band centered on the window boundary (7 days ago by default). The percentage delta is clamped at ±200% to keep recovering-from-zero rigs from dominating the sort.

A rig earning under $0.50/day on either side of the window swings wildly in percentage terms — a $0.10 to $0.50 jump is +400% but only 40¢ in real money. We demote those to Stable so the rising and falling cards surface actual movement, not divide-by-tiny.

The mover list refreshes every 5 minutes from cache. The revenue index chart refreshes every 15 minutes. Underlying RigPerformanceHistorical rows come from the hourly profitability calc jobs.

No. The percentages are computed from revenue, which is electricity-free. Your $/kWh setting only changes profit numbers on the rig detail pages.

A rig with the New badge had no recorded revenue at the start of the window — either it just shipped, or its market just woke up. The percentage delta is undefined for those rigs, so we sort them to the end of the list.

Treat rising deltas with caution. A negative delta on an established rig is almost always a real difficulty or fee change. A positive delta — especially one near the +200% cap — is usually a thin-market spike that will mean-revert. Cross-check with the rig's detail page before clicking buy.
