ZEC -2.1% in final 15m to $1,132 on 4x volume; BTC/ETH flat, cause not visible

ZEC rose slowly from $1,147 to about $1,160 by 20:45 UTC. In the last 15 minutes of the window it fell about 2.1% to $1,132.28, on spot volume about 4x normal. BTC and ETH were roughly flat, so the selling was specific to ZEC. Futures data shows little: open interest edged down, liquidations were small and funding was normal. None of the evidence names a trigger.

What happened

Price climbed from $1,147.07 (19:30) to a $1,159.62 peak (20:45) and held near $1,157–1,158 through 21:15. It then dropped to $1,132.28 by 21:28: -2.08% in 15m, -2.17% in 1h and -1.29% over the whole window. E1 E11
15-minute volume hit $3.43M against a 24h median of $0.86M (3.98x). Binance spot ZEC/USDT traded $7.6M in the last hour against a typical $3.4M (2.3x). One of the busiest minutes was 21:25: $520K traded and price fell 0.416% to $1,133.41. E2 E11
The price-move signal fired with a 1h z-score of 2.71, so the move was unusual for ZEC's recent volatility but not extreme. E11

Likely causes

1.Concentrated spot selling specific to ZEC in the final ~15 minutes. Heavy volume and a sharp price drop in the same minutes point to aggressive sellers. The taker buy/sell ratio was not available to confirm this. (55%) E2 E11 E5
2.Not driven by the wider market. BTC (-0.18%) and ETH (-0.25%) were nearly flat over the same window. (75%) E8
3.Not a leverage flush. Liquidations totalled only $212.9K ($172.3K longs) and open interest fell just 0.42% in 1h. Liquidations may have added a little to the downside but are too small to explain the move. (65%) E6 E3
4.The underlying trigger (news, a large holder, exchange flows) cannot be identified from this evidence. (80%) E1 E2 E8

Onchain

No ZEC onchain data (transfers, exchange flows) is in the evidence. The only onchain item is Ethereum's base fee: 0.05 gwei against a 0.06 24h average, with blocks 51% full. It has no bearing on ZEC. E7

Market context

The broader market was soft: total crypto market cap was down 2.73% over 24h and Fear & Greed was 55 (Greed), down from 64 a week ago. ZEC is down 7.67% over 7d. It is ranked #10 with a $19.2B market cap and is on CoinGecko's trending list. E1 E8 E9
Derivatives positioning is neutral to mixed. Funding is 0.0038% on Binance and 0.01% on Bybit and OKX, all normal. Across all Binance accounts, long/short is 0.89 (more accounts short), while top traders by position are 1.66 (net long). Open interest is $527.2M, up 1.74% over 4h. E3 E4 E5
CoinGecko sentiment is 56% positive. Developer activity is not tracked for ZEC. E10

What to watch

Whether ZEC holds about $1,130 or keeps falling on high spot volume
Taker buy/sell data once available, to confirm sell-side aggression
Binance open interest: a rise during further declines would point to fresh shorts
Long liquidations growing if top traders' net-long positions (1.66) unwind
Whether BTC and ETH follow, or ZEC keeps underperforming

Caveats

The E1 high/low fields come from 15-minute samples and miss the final drop: the reported low of $1,147.07 is above the current $1,132.28.
The taker buy/sell ratio is missing, so the direction of aggressive flow is inferred from price and volume only.
There is no ZEC-specific onchain, exchange-flow or news evidence, so the trigger is unknown.
The move happened at the very end of the window; any rebound or follow-through is not captured.
