After the 2018 midterm elections, BTC dropped from $6,400 to $3,200 in less than 40 days, exactly halving.
This week's post-election movement in the US stock market is almost identical to back then: a big surge the day after the election, followed by a 5.5% drop in the Nasdaq in one day, the largest single-day decline in 18 months. BTC reversed from 81,000 back to 76,000.
In my last analysis, the scenario was: after the election, a surge to around 80,000, then a pullback after the positive news was fully priced in. That step is now complete.
But a few things this week have made me downgrade my outlook:
The rebound was pushed back before reaching the 50-day moving average;
ETH has already broken below its previous low first;
The Federal Reserve's probability of a rate hike in December remains around 75% after the US stock market plunge;
And a historical pattern after rate hikes: in two samples, BTC dropped to a price 20% lower than the rate hike day price.
So in the detailed article, I did several things:
Mapped the 2018 timeline onto this year;
Recalculated the probabilities of four possible scenarios;
Clarified why $40,000 is worth using to test position sizing but not worth waiting for as a buy point.
The conclusion is here first: the timing window for the final drop remains unchanged, from mid-November to mid-December, but the price range has shifted down a notch, prepare for $60,000 to $73,000.
The first test will be whether $75,900 holds at the weekly close at 8 AM next Monday.

"Important: Updated roadmap for the final dip after the midterm election rebound"
November 6, 2026, Issue 114 Aspirin Data Scientist's Perspective on Cycle Analysis In the previous issue, I bet on a scenario, in which the second step was written as follows: After the election results came out, BTC would surge to between 79,500 and 80,600, then the positive news would be fully priced in and it would pull back. What actually happened this week was: On the night of the election, the highest point reached near 81,000, a bit higher than expected; on Thursday, the US stock market dropped 5.5% overnight, and BTC fell back to 76,000. The second step of the scenario was completed. I have to admit that on Wednesday, when oil prices fell below 100 and the Dow Jones surged, I once raised the probability of a "direct strengthening". But just one day later, the US stock market gave the answer. This also reminded me that one day’s news is not worth changing a week’s judgment. This issue puts together the changes before and after the election, the 2018 template, several new historical experiences, and on-chain data to update the roadmap for the next five weeks. 01 What exactly happened in these three days? November 3 was the midterm election. According to multiple media reports, the Republicans lost, and the Democrats took control of both houses of Congress. On November 4, the market initially traded on the "good news". The reason was straightforward: a change in Congress means added constraints on the executive branch, reducing the likelihood of the Iran war escalating. Brent crude oil fell from the October 23 high of 116 dollars to below 100 dollars, intraday reaching around 94 dollars; US stocks surged; BTC liquidated about 378 million dollars worth of short positions within an hour, and the spot ETF also ended a three-consecutive-

"Bearish Script Timeline"
October 26, 08:00: The second weekly candle closes below 83,000, confirming a false breakout
Following days: Retrace to the bull market support zone (just above 70,000 to 75,000), sweep the September 15 low, then rebound
October 29, 02:00: Federal Reserve meeting; if no rate hike but PCE is relatively hot that day, long-term yields may rebound, with the 10-year US Treasury returning near 5.3%
November 3: US midterm elections
Mid-November: Stock market decline drives BTC lower, long-term yields peak, forming Q4 lows
There is also a timing reference: local highs in July, August, September, and October all appeared around the 21st, except August extended to September 3. Based on this, the current peak falls between October 21 and November 3. However, with only four samples, this is for reference only.
The only condition to invalidate the entire script is if the weekly candle on October 26 closes back above 83,000.
On the night the CPI was released, both gold and BTC took a hit. Gold dropped 1.7%, and BTC swept down to 72,744.
But the more I look, the more I feel the stories behind these two assets are diverging.
I reviewed three historical periods:
In 2008, gold bottomed in October, while the US stock market bottomed 5 months later;
In 2018, gold bottomed in August, BTC lagged by 4 months;
In 2022, gold bottomed in September, BTC lagged by 2 months.
In all three cases, gold moved first. The reason is simple: gold trades on the expectation that "rate hikes are nearing an end," while risk assets wait for liquidity to truly ease.
Looking at the present, gold’s October monthly candle broke below the bull market support zone, then recovered in November, almost identical to the 2008 pattern. If gold has truly bottomed, BTC’s low will most likely fall between December and February next year, later than many expect.
In the full article, I also made a somewhat counterintuitive judgment: if BTC breaks below the July low in the next two months, 2027 could actually be better. This is because on-chain indicators will be fully cleared out, and the bottom will be more solidly established.
So my response is simple:
Gold moves first, but I’m halving my planned position size and will buy only after it stabilizes above $4,000;
BTC will be bought in batches as planned, stretching the pace to mid-January next year, avoiding high leverage.
The toughest period may be the next two months.
The full analysis is in the referenced long article, welcome to discuss.

"Gold Bottoms Out First, How Much Longer for BTC?"
November 11, 2026, Issue 114 Aspirin Data Scientist's Perspective on Cycle Analysis On the evening of November 10, the US October CPI was released, hotter than expected: overall month-on-month increase of 0.4%, expected 0.3%; core month-on-month increase of 0.3%, expected 0.2%. Fed Governor Waller previously said that with the core around 0.3%, a 50 basis point rate hike should be considered in December. Once the data was released, two assets with completely different trends this year both took a hit. Gold fell 1.7%, back to around $4,050; BTC swept down from 75,000 to 72,744, then recovered to 74,700 within a day. Both fell on the same day, but I believe the stories behind them are diverging. This issue puts together the recent two weeks' materials on gold and BTC to clarify one thing: why gold has very likely already bottomed first, while BTC's final phase is not yet over. 01 Gold: Just a deep correction, the bull market will continue First, look at the retracement magnitude. Gold has retraced about 30% from its high. This figure is not outrageous historically: the 2006 retracement was about 25%, 2008 about 34%, 2022 about 22%, after which new highs were made again. Next, look at the most critical technical signal. For gold, the bull market support zone is seen on the monthly chart, specifically the 20-month moving average and the 21-month exponential moving average. October's monthly candle closed below the support zone, but November has reclaimed it. This pattern is almost identical to October 2008: back then also

Binance was hacked for $6.3 billion, with $1.5 billion liquidated overnight, yet BTC only dropped to a low of 76,642.
It just hit the 21-week moving average, only 30 dollars short.
Honestly, I was quite surprised to see this candlestick. Such a major bearish event couldn't break through, which indicates someone is buying at the bottom. But I don't think the bottom has been reached yet; volume hasn't picked up, and panic hasn't set in.
So I reviewed all the cycles, on-chain data, moving averages, and macro factors I've been watching these past two weeks and wrote a long article.
What concerns me most is a coincidence: three completely unrelated methods all point to the same range, 70,000 to 74,000. After doing cycle analysis for so long, this is rare.
My judgment is that it will hold first, then drop. It will likely hold before the election, possibly even rebound near 80,000, but the final drop may not be over. The timeframe I’m focusing on is November 16 to 21, the week Anthropic goes public.
Of course, I could be wrong. So in the long article, I clearly explain how to respond to each possible scenario and when to admit being wrong.
The first test point is the weekly close at 8 AM next Monday; whether 75,900 holds is critical.

"Hold First, Then Fall: The Timing and Price of the Last Drop in This Cycle"
2026年10月30日 第112期 Aspirin 数据科学家视角的周期分析 周三晚上币安被盗的消息出来，涉及资金约63亿美元，冻结约30亿，充提全部暂停，全网一晚上爆仓超过15亿美元。按以往的经验，这种级别的利空足够砸出一根长阴线。结果比特币最低只到76,642，刚好踩在21周均线76,612上，几乎分毫不差。 这件事本身就是一条数据。它说明现在的卖盘还不是恐慌盘，市场底下有人在接。但它不能说明底部已经出现，因为真正的周期低点通常伴随着成交量的集中释放，而这一次并没有。 这一期我把最近两周所有的线索放在一起：周期时间、链上成本、均线结构、宏观节奏，最后给出我认为概率最高的一条路径，以及对应的打法。 01 我们站在周期的哪个位置 这一轮的高点是2025年10月6日的12.6万，今年7月出了一个5.77万的低点。以2022年11月的熊市底部为起点，今天是第1439天。前两轮周期分别在第1432天和第1436天见到低点，所以从时间上看，低点窗口已经打开。 另一个时间规律来自中期选举年。历史上，中期选举年的四季度低点基本都出现在选举之后。今年的选举在11月3日，这意味着窗口很可能落在11月中
"Hold First, Then Fall: The Timing and Price of the Last Drop in This Cycle"
October 30, 2026 Issue 112 Aspirin Cycle Analysis from a Data Scientist's Perspective On Wednesday night, news broke of a Binance hack involving about $6.3 billion in funds, with approximately $3 billion frozen, and all deposits and withdrawals suspended. The entire network saw liquidations exceeding $1.5 billion overnight. Based on past experience, a negative event of this magnitude is enough to trigger a long bearish candlestick. However, Bitcoin's lowest point only dropped to 76,642, just landing on the 21-week moving average at 76,612, almost exactly. This event itself is a piece of data. It indicates that the current sell-off is not yet panic selling; there are buyers at the market bottom. But it does not prove that the bottom has appeared, because a true cycle low is usually accompanied by a concentrated release of volume, which did not happen this time. In this issue, I put together all the clues from the past two weeks: cycle timing, on-chain cost, moving average structure, macro rhythm, and finally present what I believe is the most probable path along with the corresponding strategy. 01 Where we stand in the cycle The high point of this round was 126,000 on October 6, 2025, and a low of 57,700 appeared in July this year. Starting from the bear market bottom in November 2022, today is day 1,439. The previous two cycles saw lows on days 1,432 and 1,436 respectively, so from a timing perspective, the low window has opened. Another timing pattern comes from the midterm election year. Historically, the fourth-quarter lows in midterm election years generally occur after the election. This year's election is on November 3, which means the window is very likely to fall in mid-November
PCE is out, and the result is lukewarm; gold, silver, and the dollar barely moved. But looking closely at this set of data, there's quite a bit of information.
Core PCE for September year-over-year is 3.1%, slightly higher than last month's 3.0%, and month-over-month is 0.3%, all in line with expectations. Inflation is not out of control, but there's no sign of it easing either, so the case for a rate hike in December remains.
At the same time, Q3 GDP annualized growth is 3.4%, stronger than the expected 3.2%, and up from 2.2% last quarter. With such a strong economy, the Federal Reserve has no reason to rush to ease. The only somewhat dovish point is the GDP price index, which is only 2.3%, well below the expected 3.2%.
My understanding is that tonight's data doesn't vote for any particular path. A strong economy and core inflation not falling support a December rate hike and could push 10-year Treasury yields higher, which favors the bearish scenario. But with GDP this strong, it's hard to see recession fears and a major stock market drop in the short term. Plus, WTI has already fallen back to around $101, so the move to $120 oil is stalled for now, which may weaken the bearish scenario somewhat.
So, the next move is up to the market price. I'll be watching three things. First, the weekly candle at 8 a.m. on November 2: if BTC closes below 83,000, the main path continues; if it closes above, a shift is likely. Second, whether the 10-year Treasury yield will surge to 5.3% due to the strong economy. Third, whether this pre-election rally will be resisted around BTC 80,000 to 82,000.
When the market doesn't give answers, the best move is to wait.
Tonight's 8:30 PCE may determine how BTC will move over the next month or so. I've written the complete roadmap in a long article; here I'll just share the key points.
The Fed did not raise rates last night, but the vote was 10 to 2, with two members calling for a hike. The probability of a rate hike in December has risen from 36% to 78% in the past month. The PPI year-on-year has already reached 6.35%, and the expected PCE tonight is 3.6%. I believe there's a 60-70% chance it will be on the hot side.
If it's hot, my timeline is as follows: BTC will first return to around 78,000, with one last rally before the election, but it will be difficult to break above 83,000. The real drop will come after the November 3 election, initially targeting 67,000 to 70,000. November 16 to 20 is Anthropic's IPO week; BTC bottomed around the time of SpaceX's IPO this year, so this week is the first low point window.
If it's cold, with two consecutive weekly closes above 83,000, this scenario is invalidated, and the target shifts to 87,300 and 90,000.
I will watch three signals: tonight's PCE, the weekly close on November 2, and whether the 10-year US Treasury yield will surge to 5.3%.
The timing, price points, and conditions for each step are all detailed in today's long article. Friends who want to prepare in advance can take a look.
This is my personal opinion and does not constitute investment advice.

"After the Interest Rate Decision, Two Paths for BTC in Q4"
2026年10月29日 星期四 第四季度 第111期 Aspirin 数据科学家视角的周期分析 今晚八点半公布的9月PCE，是接下来一个多月行情的分岔口。我的判断是，数据偏热的可能性更大，那样的话BTC会先跌一段，选举前再弹一次，选举后迎来四季度的最后一跌，低点大概落在11月中旬到12月10日之间。如果数据偏冷，这套空头剧本就可能作废。 01 剧本走到了哪一步 10月26日，BTC第二根周线收在8.3万下方，这次突破基本可以确认是假突破。昨晚美联储按兵不动，但态度比市场想的更鹰，投票是10比2，有两位委员直接主张加息，12月加息的概率一个月里从36%涨到了78%左右。 接下来就看今晚的PCE。市场预期3.6%，上个月是3.4%。PPI同比已经跳到6.35%，我认为偏热的概率在六到七成。 盘面上，BTC议息后冲到8.17万就被压了回来，现在在7.98万附近。ETH更弱，已经跌破2,328的支撑。 02 如果PCE偏热 数据一出，长端利率会先往上走，BTC大概率回到7.8万附近，那里是100日均线，ETH则可能跌破2,283，看到2,200上下。 10月30日下午有一笔大规模的期权交割，之
"After the Interest Rate Decision, Two Paths for BTC in Q4"
Thursday, October 29, 2026, Q4, Issue 111
Aspirin Data Scientist's Perspective on Cycle Analysis
The September PCE, to be released tonight at 8:30, is a critical turning point for the market over the next month or so. My judgment is that the data is more likely to be hot; if so, BTC will first drop for a while, then bounce once before the election, and after the election, face the last drop of Q4, with the low point roughly between mid-November and December 10. If the data is cold, this bearish scenario might be invalid.
01 Where the scenario stands
On October 26, BTC's second weekly candle closed below 83,000, confirming that this breakout was basically a false breakout. Last night, the Federal Reserve held steady, but its stance was more hawkish than the market expected. The vote was 10 to 2, with two members directly advocating a rate hike. The probability of a rate hike in December rose from 36% to about 78% within a month.
Next, all eyes are on tonight's PCE. The market expects 3.6%, last month was 3.4%. The PPI year-on-year has already jumped to 6.35%, so I believe the probability of hot data is about 60-70%.
On the market, BTC surged to 81,700 after the rate decision but was pushed back, now hovering around 79,800. ETH is weaker, having already broken the 2,328 support.
02 If PCE is hot
Once the data is out, long-term interest rates will likely rise first. BTC will probably return to around 78,000, which is the 100-day moving average. ETH may break below 2,283 and see levels around 2,200.
On the afternoon of October 30, there is a large-scale options expiration, which
Today, BTC weekly chart broke below 83,000 twice, confirming a false breakout. I predict one last drop in Q4, with the low point around the December rate decision.
Starting points: BTC 80,000, ETH 2,310, Gold 4,011, 10-year US Treasury 4.99%, Brent crude $115.
October 26-28: BTC retests bull market support zone at 74,000 (72,000 to 76,000)
October 29 02:00: Fed holds rates steady, leaving room for a hike in December
October 29 20:30: September PCE hotter than expected, BTC rebounds to 77,000 but faces resistance at 82,000
October 30 16:00: $10.9 billion BTC options expire
November 3: Midterm elections, BTC fluctuates between 74,000 and 79,000
November 4-25: US stocks catch down, Brent breaks $120, 10-year yield surges to 5.3%, BTC first drops to 67,000
December 10 03:00: Rate hike to 4.00%-4.25%, dollar peaks, BTC bottoms at 60,000 (extreme 55,000)
December 31: Long-term yields fall back, BTC closes at 66,000
Target prices (December low / year-end):
BTC: 60,000 / 66,000
ETH: 1,500 / 1,680
Gold: 3,780 / 4,050, bottoming first
Invalidation condition: Weekly close back above 83,000. Until then, I remain bearish.

2026年10月26日 · 星期一 第四季度 · 第110期 Aspirin · 数据科学家视角的周期分析 今天早上8点，BTC第二根周线收在8.3万下方。我的判断很明确：这次突破是假突破，四季度还有最后一跌。BTC的低点会出现在12月10日美联储议息前后，位置在6万附近；黄金会先于BTC见底回升，白银最弱。 下面是完整剧本、时间表和点位。 01｜为什么说假突破已经确认？ 8.3万是5月高点。一根周线收在下方可以算回踩，连续两根就是证伪。现在价格约8万，日线也已经跌破50日均线（约8.17万）。 历史上几次假突破，出清都很快。2015年和2020年，从第二根周线跌破到见底，只用了两到三周。所以接下来不会是慢慢阴跌，而是一段集中、快速的下跌。 还有一个信号：纳斯达克、标普、道指、ETH和山寨币总市值都已经回测过牛市支撑带，BTC是最后一个还没测的。我不认为它会例外。 02｜宏观在往同一个方向推 美联储本周按兵不动，市场已经计价约94%，所以真正的看点是声明里对12月的措辞。9月PCE一旦偏热，市场就会确认：12月还要加息。 10年期美债现在约4.99%，我认为届时会回到5.3%；布伦特原
