The euphoric melt-up flagged last scan cooled hard and uniformly across the entire coin tier — DOGE's RSI collapsed from the most extreme reading tracked in this window (95.7) to 52.8, XRP from 86.8 to 64.4, and ADA and DOGE both fell back below their 200-day, downgraded from parabolic all the way to downtrend. But read against the one-year window, this reads as a cooldown from an extreme, not a renewed crash: BTC held its 200-day cushion (+11.6%, was +12.1%) and its one-year deficit stayed essentially flat (-28.57%, was -28.55%) — still the least-damaged asset in the coin tier by a wide margin. Every coin's one-year return stays negative (BTC -28.57%, ETH -44.78%, SOL -48.47%, XRP -50.36%, ADA -75.31%, DOGE -61.9%, AVAX -68.99%, DOT -77.27%, LINK -51.12%) and alpha1y stays negative across the board — the melt-up cooled without repairing a year of underperformance. A broad, synchronized single-day pullback hit the entire complex on this scan's final session — BTC -3.67%, ETH -3.44%, SOL -5.23%, DOGE -11.11%, MSTR -7.34%, COIN -6.33%, RIOT -9.05%, CLSK -9.96%, MARA -10.11% — this desk checked the news receipts for MSTR and COIN (both fetched within the prior 24-72 hours, ok, not stale); neither surfaced a name-specific negative catalyst, consistent with a broad risk-off day rather than a single-name event. The miner cohort's divergence from last scan partially resolved: RIOT's 30-day print improved to +4.11% from -15.18%, no longer the standout laggard, while MARA's regime was downgraded further to collapse (30D +6.17%, vs-SMA200 flipped negative to -2.8% from +1.5%). MSTR's 200-day cushion narrowed sharply toward a flip (-9.7%, was -17.2%) even as its price fell -7.34% on the final session — a genuine improvement in the medium-term trend colliding with a sharp single-day drop.

All entries in this scan carry a uniform 2026-08-28 close — coins, spot ETFs, and crypto equities alike — resolving the split-basis flag from the prior scan (crypto trades weekends; that scan's ETF/equity leg was still on the prior Friday's close). Source: crypto. Prior scan: 2026-08-22-crypto-scan (2026-08-22 coins / 2026-08-21 ETFs and equities — split basis).

Last scan's alt-season rotation reversed uniformly this scan: every coin's 7-day return flipped negative or sharply decelerated — ADA -13.04% (was +27.78%), DOGE -11.11% (was +28.57%), XRP -4.83% (was +51.0%), LINK -5.42% (was +24.21%), AVAX -7.4% (was +19.59%), DOT -9.57% (was +22.37%), SOL +10.52% (was +25.6%, still positive but decelerating sharply), ETH -3.63% (was +29.6%). BTC's own 7-day print is -1.3% (was +22.71%) — smaller in magnitude than most of the alt cooldowns, meaning BTC's relative resilience this cycle mirrors last cycle's relative-outperformance-on-the-downside pattern. On the one-year window, BTC's -28.57% deficit remains the smallest in the entire coin tier by a wide margin, essentially unchanged from -28.55% — every alt still underperforms BTC by a wide margin over the past year (DOT -77.27%, ADA -75.31%, AVAX -68.99%, DOGE -61.9%, LINK -51.12%, XRP -50.36%, SOL -48.47%, ETH -44.78%). This scan's uniform cooldown is a mirror of last scan's uniform melt-up — the underlying one-year relationship between BTC and the alts didn't change.

All four spot-BTC/ETH proxies (IBIT, GBTC, ETHE, BITO) cooled in lockstep with their underlying coins — no regime downgrades this scan (all held their upgraded pullback/parabolic/downtrend labels from last scan), tracking price direction rather than showing an independent divergence. As in prior scans, this JSON carries no independent flow data — the ETF layer remains a pure price-tracking proxy, and its uniform cooldown this scan simply confirms the coins' own reversal, not an independent signal.

The miner cohort's divergence from last scan — where RIOT and CLSK fell while the rest of the universe melted up — partially resolved this scan. RIOT ($18.99, RSI 43.4) saw its 30-day print improve sharply to +4.11% from -15.18%, no longer the standout laggard it was last scan, though it fell -9.05% on the final session alongside the rest of the complex. CLSK ($11.66, RSI 44) improved its 30-day print to -2.91% from -21.85% but stayed negative, with its regime still collapse. MARA ($10.67, RSI 47.9) moved the other direction — its regime was downgraded further to collapse and its vs-SMA200 flipped negative to -2.8% from +1.5%, even as its 30-day print turned positive (+6.17%, was -9.27%). BITQ ($24.67, RSI 52.9) cooled from last scan's improvement but stayed positive on the year (+21.47%). All four miners retain their golden cross on the long-run signal; RIOT, CLSK, and BITQ all carry positive one-year returns (+37.61%/+22.09%/+21.47%) — still a genuinely different long-horizon picture than the coins themselves, where every name is negative on the year.

Both fell sharply on the final session — MSTR -7.34%, COIN -6.33% — alongside the rest of the complex, but their medium-term pictures diverged. MSTR's vs-SMA200 cushion narrowed sharply to -9.7% from -17.2%, a genuine improvement in the medium-term trend even as the single-day drop was the sharpest of the two names; its 30-day print stayed strongly positive at +36.41% (was +19.24%). COIN's 200-day gap widened slightly to -8.6% (was -6.1%) and its 30-day print cooled to +11.59% (was +12.26%). Both remain death-crossed and deeply negative on the one-year window (MSTR -62.43%, COIN -42.09%). This desk checked both names' news receipts this session (MSTR fetched 2026-08-27, ok, not stale; COIN fetched 2026-07-31, ok, not stale but older) — MSTR's most recent headline is a bullish "cash war chest" piece dated the day before this session's drop, and neither pull surfaces a name-specific negative catalyst for the Friday session's decline.

Support shelves on record this scan: BTC $70,582.20 (unchanged), ETH $2,252.87 (down from $2,296.50), SOL $88.53 (unchanged), AVAX $6.32 (unchanged), LINK $8.99 (down from $9.18), IBIT $40.15 (unchanged), GBTC $55.13 (unchanged), ETHE $18.50 (down from $18.73), BITO $8.69 (unchanged), MSTR $99.52 (roughly flat vs. $99.67), COIN $166.51 (down from $177.47), MARA $9.81 (down from $10.51), RIOT $18.17 (down from $18.74 — price at $18.99 now sits closer to this shelf than last scan), CLSK $10.28 (down from $11.58), BITQ $23.74 (unchanged) — XRP, ADA, DOGE, and DOT still carry no support shelf on record. DOT's -82.55% and ADA's -78.95% off their 52-week highs remain the widest drawdowns in the coin tier. RIOT's price sits within roughly 4% of its own newly-lowered shelf, the closest of any equity in this universe.

No coin, ETF, or equity in this universe is oversold this scan — the RSI floor across the entire universe is DOT at 51.9 — but the near-universal overbought reading flagged last scan (DOGE at 95.7) has cooled sharply across the board, with only ETHE (76.1) and SOL (73.6) still meaningfully extended. Read purely as a risk-appetite gauge, this reads as a broad cooldown from euphoria rather than a fresh risk-off regime — RSI readings across the coin tier now sit in a 52-74 range rather than the 76-96 range flagged last scan. The synchronized final-session decline across coins, miners, and MSTR/COIN together (all down 3-11% on the day) is the more informative signal this scan: this desk checked news for the largest single-day movers (MSTR, COIN) and found nothing name-specific, consistent with a broad risk-off session rather than a name-specific event. This crypto.json summary carries no cross-asset field, so a direct correlation-to-equities read isn't computable from this data.
