How to read MiningBoard's rig profitability trends
Updated May 2026 · A guide to /trends
Every leaderboard on this site ranks rigs by current revenue. The Trends pages do the opposite — they rank rigs by how fast that revenue is changing. If you're shopping, that change matters more than the snapshot: a rig dropping 30% in a week may be tomorrow's bargain or tomorrow's brick, and a rig climbing 20% may be catching a fee spike that will reverse by Friday.
What the page actually does
For every rig in a device class, we compute two numbers:
- Current revenue — the average
RigPerformanceHistorical.revenue_mili_centover the last 24 hours. - Prior revenue — the average over a 2-day band centered on the window boundary (7, 30, or 90 days ago).
The delta is (current − prior) / prior × 100, clamped to ±200%
so a rig recovering from near-zero doesn't dominate the sort. Anything
earning under $0.50/day on
either side of the window gets demoted to Stable regardless of
its % delta — a 40-cent swing on a 10-cent baseline is arithmetic-correct
but operationally noise.
Status badges
The badge next to each rig is a coarse summary of the delta:
| Badge | Rule | What it means |
|---|---|---|
| Rising | Δ ≥ +5% | Revenue noticeably higher than the window start. |
| Falling | Δ ≤ −5% | Revenue noticeably lower. |
| Stable | −5% < Δ < +5% | Inside the noise band. |
| New | prior = 0 | No revenue on the prior side of the window. Sorts to the end so it doesn't poison the % ranking. |
Why four separate pages
ASICs and GPUs respond to different forces. Mining ASICs move with coin price and network difficulty — those re-target on a 2-week cadence, so a 7-day window catches real movement. GPU AI-rental rates are governed by data-center supply contracts and quarterly capex cycles; the daily noise is huge and only a 30-day window separates signal from chop.
That's why /trends/asic and /trends/gpu default to 7-day windows, while /trends/ai-rental defaults to 30 days. Use the pill selector at the top of any page to switch.
What's moving right now
How a buyer should read them
- Start with the chart. If the average revenue line at the top of the page is sloping down across the window, the whole class is softening — that's a macro signal that no individual mover will offset.
- Trust falling over rising. A negative delta on an established rig is almost always a real fee or difficulty change. A positive delta near the +200% cap is usually a thin-market spike that will mean-revert.
- Cross-check with the rig detail page. Click through to the rig and look at the historical chart on its overview tab. If the delta is purely from the last 12 hours, treat it as noise.
- Watch the "New" rigs. A rig with the New badge has only just acquired tracked revenue. It may be a fresh model release or a market that just woke up — both are useful signals, but neither is comparable to the other rigs in % terms.
Refresh + cache
Each device delta is cached for 5 minutes; the chart series is cached for
15 minutes. Revenue is ecost-free, so the cache is global rather than
per-visitor — your $/kWh setting
only affects profit math on rig detail pages, not the Trends % deltas.
Limitations
- Rigs with only deprecated algorithms are excluded — we can't price them.
- CPU coverage is thin compared with ASIC/GPU. Many CPUs show as "New" simply because we haven't collected prior-window data for them yet.
- The 24-hour current window means a single bad scrape or pool downtime will move a rig's delta. We accept that noise to keep the page reactive.
- There's no popularity signal yet (e.g. provider count or click-through). We're working on that — it's the next layer.
