Bitcoin's 200-day line, the golden cross and Uptober: we tested all three

None of the three passed. The 200-day rule made 14.2% a year against 62.8% for holding the same coins, with a smaller worst drop. The golden cross made 14.8%. Holding only in October made 9.2% a year and beat 158 of 200 random copies, short of the 190 the bar asks for.

What people say

Every autumn the same three ideas come round on crypto social media. A bull market is confirmed once price holds above the 200-day moving average for a month. A golden cross, the 50-day average crossing above the 200-day, means the bear market is over. And October is so reliably good that it has a name, Uptober.

• "closes above its 200 Day Moving Average for at least 30 days" (r/CryptoCurrency post, 24 Sep 2026)
• "Bitcoin Chart Flashes Golden Cross. Is the Bear Market Finally Over?" (r/CryptoCurrency post title, 9 Sep 2026)
• "a sort of mythos known as Uptober" (Sam Daodu, 24/7 Wall St, 1 Oct 2026)

The 200-day post above drew 125 upvotes and 116 comments on r/CryptoCurrency. Lark Davis's "Bitcoin Enters Uptober" video passed 24,000 views in two days. The same 24/7 Wall St article notes that the Fed meeting at the end of October may matter more than the calendar.

What we tested

We coded each idea as a rule you could follow with no judgment, ran all three on the same 18 coins, and wrote the rules and the pass bar down before running.

• Long after 30 closes above the 200-day average, out on a close below. Buy once a coin has closed above its 200-day simple average for 30 days in a row. Sell on the first close below the average.
• Golden cross: long while the 50-day is above the 200-day. Hold while the 50-day simple average is above the 200-day (the golden cross), cash after the death cross.
• Uptober: hold through October only. Hold every day of October, cash for the other eleven months.

Results

One thing to know before reading the numbers. The benchmark is always fully invested, and from 2017 to early 2025 crypto rose a lot, so any rule that spends much of its time in cash trails it by a wide margin almost automatically. That is why we also compare each rule with 200 copies of itself: the same number of trades, the same holding times and the same costs, moved to random dates. Those copies are in the market exactly as much as the rule is, so they answer the fairer question: did the rule pick better moments than chance? The 200-day rule was in the market 28% of the time, the golden cross 45%, and Uptober 9%.

The charts show the 200-day rule. It beat 49 of 200 random copies: its timing was not better than chance.

What costs do to it

Crypto pays 0.10% a side plus a measured slippage for each coin; US stocks and ETFs pay 0.05% a side. The cost is charged every time the position changes, including a flip from long to short. These rules trade rarely (127, 133 and 111 trades across 18 coins), so costs barely matter: the 200-day rule made 14.5% a year before costs and 14.2% after.

Why they did not hold up

Trend filters on crypto do one thing well: they step aside in long crashes. The 200-day rule's worst drop was 63.4% against 85.9% for holding. The price is missing the fast early part of every rally while waiting for 30 days of confirmation, and in this window that cost more than the crashes saved. Its timing beat 49 of 200 random copies.

The golden cross is the same story with slower averages. It made 14.8% a year, beat 7 of 200 random copies, and did worse than the basket in both halves of the window.

Uptober is the closest call. Holding only October beat 158 of 200 random copies of itself (the same month-long holds moved to random dates), which is better than average but short of the 95% the bar requires, and it was ahead of the basket in only one of the two halves. Seven or eight Octobers is a tiny sample, and a single month of crypto can move a long way in either direction.

What a beginner should take away

• The 200-day line and the golden cross are risk tools, not return tools. In our test they cut the worst drop and cut the return by more.
• A seasonal pattern needs many more years than crypto has before it means much. Seven Octobers is not enough.
• If you use a trend filter, decide in advance what you will give up for a smaller drawdown. Do not expect it to beat holding.

Try it yourself

The Lab has no crypto, but the 200-day rule runs on any daily stock: on QQQ, set the entry to price crosses above sma(200) and the exit to price crosses below sma(200). The Lab's data starts in mid 2024, so the 200-day line needs most of a year to warm up.

• Open the Backtest Lab with QQQ loaded (free account)

The Lab tests one rule on one stock, fills at the next open and compares against holding that stock after costs, so its number will not match the basket results above.
