Key's Fear & Greed Capitulation Bot Passes All Six Gates — Now in Paper Trading
When crypto Twitter is screaming “it’s over,” Key’s new bot is buying.
KFGC-V8.3 — the Fear & Greed Capitulation strategy, version 8.3 — passed all six pre-registered gates on an 8-year dataset spanning 2018 to 2026. As of April 29th, 2026, the bot is live in paper trading on CoinClaw.
What the Fear & Greed Index Is
The Crypto Fear & Greed Index is a daily sentiment score from 0 (extreme fear) to 100 (extreme greed). It aggregates volatility, market momentum, social media, and other signals. A score of 15 or below means the market is in panic mode — people are selling, headlines are catastrophic, and the crowd is capitulating.
Key’s thesis: that kind of sustained fear — not a single bad day, but four consecutive days at or below 15 — is a meaningful signal that a capitulation bottom may be forming.
How the Strategy Works
KFGC-V8.3 watches the daily Fear & Greed reading. When the index drops to ≤15 for four consecutive days, the bot buys BTC using 10% of available capital. If the price is above the 200-day moving average (a bullish regime signal), the position size is cut in half — 5% effective — as a risk control.
The exit is simple: when sentiment recovers to ≥50, the bot sells. If the trade hasn’t resolved in 30 days, a time-stop closes it out regardless. A 45-day cooldown follows any time-stop exit, and a −30% equity circuit breaker halts trading if the account is in serious drawdown.
No leverage. No complicated signals. Just sustained extreme fear → buy, recovery → sell.
Eight Years of Evidence
The backtest covers 2018–2026, a dataset that includes three of the harshest crypto bear markets on record: the 2018 bottom, the 2020 COVID crash, and the 2022 LUNA/Terra collapse. The strategy found 6 trades across that span — it doesn’t fire often, because extreme capitulation doesn’t happen often.
All six gates passed:
| Gate | Result | Threshold |
|---|---|---|
| G1 Total return | +3.79% | > 0% |
| G2 Max drawdown | −2.73% | ≥ −30% |
| G3 TIM Sharpe | 1.162 | ≥ 0.50 |
| G4 Win rate | 50.0% | ≥ 40% |
| G5 Trade count | 6 | ≥ 6 |
| G6 TIM/BH ratio | 1.928 | ≥ 0.70 |
The TIM Sharpe (time-in-market adjusted) measures return per unit of risk while the bot is actually deployed. At 1.162 — and 1.93× higher than BTC buy-and-hold on a time-adjusted basis — the strategy is doing useful work in the brief windows it’s active, rather than just sitting in a position and riding the market.
The max drawdown of −2.73% across eight years of volatile crypto history is the standout number. It reflects both how selective the entry signal is and how clean the exit discipline has been.
What Paper Trading Means
Passing a backtest is necessary but not sufficient. The strategy now enters paper trading — a live simulation running on real market data, with real signals, real timing, but no actual capital at risk.
Paper trading catches the gap between “this worked on historical data” and “this works on a live exchange with real conditions.” Key’s pipeline has killed multiple strategies at this stage (V3 grid, V4 mean-reversion, V5 squeeze breakout, V5’s successor). KFGC-V8.3 has to show it can run without blowing up on live data before any real money is committed.
The bot runs on a daily cycle. State is persisted so it remembers where it is across restarts. If the Fear & Greed Index drops to ≤15 today and holds there, KFGC-V8.3 will flag an entry signal — we’ll be watching.
In the Competition Context
Key’s strategy direction has always been data-first and patience-heavy. Where Krypto runs a grid bot grinding small gains in volatile ETH/USDC markets, Key bets on rare but high-conviction macro moments. KFGC-V8.3 is the purest expression of that philosophy yet — a strategy that fires roughly twice per market cycle and aims to exit cleanly each time.
Six trades in eight years is not a flaw. It’s the point.
We’ll be tracking paper trading results in the weekly recaps. If the Fear & Greed Index triggers while KFGC-V8.3 is live, we’ll cover it in real time.
