'First Three Straight Monthly Gains Since 2012' Fails a Monthly-Close Check: Yahoo Shows 11 Such Streaks 2015-2025 (Latest Apr-Jul 2025); the Rarity Is an All-Green Jul-Sep, Last 2012/13; Sept Isn't Closed and Needs $78.5K; 13 of August's 25 Points Came in Two Days, Sept Tracks ETF Flows Daily
The parent card (and its Crypto Briefing source, published 23 Sept 2026 10:03 UTC) says Bitcoin "has posted three consecutive months of price gains for the first time since 2012". Checked against monthly closes, that is wrong. Yahoo Finance BTC-USD monthly closes (CCC composite, fetched 23 Sept 2026) show eleven completed runs of three or more consecutive positive months between 2015 and 2025 alone: Sep-Dec 2015 (four), Apr-Jun 2016 (+7.6%, +18.5%, +26.7%), Sep 2016-Feb 2017 (six), Apr-Aug 2017 (five: +25.8%, +69.6%, +8.5%, +15.9%, +63.6%), Oct-Dec 2017, Feb-Jun 2019 (five), Oct 2020-Mar 2021 (six: +27.8%, +42.4%, +47.8%, +14.2%, +36.3%, +30.5%), Jan-Apr 2023 (four, with Feb 2023 at +0.03%), Sep 2023-Mar 2024 (seven), Sep-Nov 2024 (+7.4%, +10.9%, +37.4%) and Apr-Jul 2025 (four: +14.1%, +11.1%, +2.4%, +8.0%). Blockchain.com's averaged market-price series (fetched 23 Sept 2026) adds Jan-Apr 2013 (+48.2%, +55.5%, +195.8%, +56.3%) and Jul-Sep 2013 (+13.5%, +15.8%, +1.7%). The most recent qualifying streak ended fourteen months ago, not fourteen years ago.
What the source appears to have garbled is a narrower and genuinely rare statistic: July, August and September all closing green in the same calendar year. On Yahoo data no third quarter from 2015 through 2025 managed it: September was red in 2017 (-7.8%), 2020 (-7.7%) and 2021 (-7.2%); August was red in 2015, 2016, 2018, 2022, 2023, 2024 and 2025 (-6.5%); 2019 was red all three months. Blockchain.com gives 2012 as Jul +38.2%, Aug +18.3%, Sep +14.5%, then Oct -12.6% (Crypto Briefing quotes +41.0%, +6.4%, +24.4% and -9.7% from a different exchange feed; the Mt. Gox era has no single canonical print). The same series shows Sept 2013 at +1.7%, i.e. a second all-green Q3, while Coinglass-style tables put Sept 2013 at roughly -1%. So the defensible claim is "first all-green third quarter since 2012 or 2013, depending on data source", not "first three-month winning streak since 2012". The article's other precedent number is also off: from the Oct 2012 close of about $11 to the Nov 2013 monthly close of $1,134 is over +10,000%, not "exceeding 2,000%" (true, but understated five-fold).
The streak is also not yet a fact. Yahoo's 2026 monthly closes are: Jan $78,621 (-10.2%), Feb $66,996 (-14.8%), Mar $68,233 (+1.8%), Apr $76,304 (+11.8%), May $73,580 (-3.6%), Jun $58,559 (-20.4%), Jul $62,814 (+7.3%), Aug $78,549 (+25.1%). Against the $78,549 August close, spot of about $85,450 at 12:20 UTC on 23 Sept (CoinGecko) is +8.8% month-to-date, so the third green month survives any drawdown smaller than 8.1% before 30 Sept 23:59 UTC. Source discrepancies: Crypto Briefing has July at +4.8% and September at +10.9%; Yahoo has July at +7.3% and September at +10.3% as of the 22 Sept close of $86,603 (August, +25.2% vs +25.1%, agrees). The parent's "reclaimed approximately $87,000" is accurate as an intraday print ($87,251 early 22 Sept and $87,374 on 21 Sept per Bitcoin.com News, the highest since late January) but not as a level held: the 22 Sept close was $86,172 and spot is back near $85,450. For scale, the rebound is +48% from the 1 July 2026 low of $57,748, yet BTC is still -2.3% year-to-date against the $87,509 December 2025 close and 32% below the $126,198 all-time high of 6 Oct 2025 (Yahoo daily). Three green months have so far only undone the first-half drawdown.
What actually produced the three months, from Yahoo daily closes: July was a grind, +7.3% with its largest day +4.4% on 14 July. August's +25.1% was mostly two sessions: the close went from $64,681 on 18 Aug to $69,266 on 19 Aug (+7.1%) and $73,033 on 20 Aug (+5.4%), a two-day +12.9% that Bitcoin.com News attributes to the U.S. Treasury's bond-buyback announcement, followed by +7.3% on 21 Aug to $78,335. Strip out 19-20 Aug and August was +3.0% to the 18th and +7.6% from the 20th to the 31st. Alternative.me's Fear and Greed index went from 27-34 (10-17 Aug) to 62 on 20 Aug and 71-74 by 21-25 Aug. September's move lines up almost day for day with spot-ETF flows (Farside, fetched 23 Sept 2026): net outflows of $1.05B across 8-16 Sept coincided with the month's only sizeable red day (-3.3% on 15 Sept to $75,613, the day of the -$450M print), then +$2.31B across 17-22 Sept ($159M, $433M, $999M, $715M) coincided with +5.9% on 18 Sept and +6.7% on 21 Sept to the $86,603 high close. The $999M day on 21 Sept was $381M IBIT, $289M ARKB and $239M FBTC, and Bitcoin.com quotes it as one of the largest single-day inflows in 11 months; Farside's Sept net since 4 Sept is +$1.43B, all of it and more from the last four sessions. Bitcoin.com also reports Coinglass short liquidations of $454M on 21 Sept collapsing to $48M on 22 Sept as long losses rose to $14M, i.e. the squeeze has run out of shorts. On the policy side its Rootstock source lists the SEC innovation exemption, the American Reserve Modernization Act clearing committee, and a Bank of Japan hike with a weaker yen; those are narrative, the flows are the measurable driver. The $16B 25 Sept Deribit expiry sits inside the remaining window and is the one scheduled event that can move the monthly close.
Forward returns after prior streaks and Q4 seasonality are a separate question (covered in a companion card); the short version is that the month after a completed three-month streak was up 8 of 11 times in the Yahoo series with a 2018-sized left tail, which is mild evidence, not a regime signal.
What to watch: the 30 Sept close relative to $78,549 (the streak), whether ETF flows stay positive after the 25 Sept expiry, and whether Fear and Greed (78 on 22 Sept, 71 on 23 Sept) pushes into the 80s where August's buyers get tested. The headline "first since 2012" should not be repeated; the honest version is "possibly the first all-green third quarter in 13 or 14 years, pending the monthly close, and the gain was two August days plus a September ETF bid."

Key Takeaway
The 'first three straight monthly gains since 2012' claim is a data error: Yahoo monthly closes show eleven such streaks from 2015-2025 (latest Apr-Jul 2025); the true rarity is an all-green July-September (last 2012 or 2013 depending on source), it is not confirmed until BTC closes 30 Sept above the $78,549 August close, and the gain itself was 13 August points in two sessions plus a September move that tracks spot-ETF flows day by day.
The parent card (and its Crypto Briefing source, published 23 Sept 2026 10:03 UTC) says Bitcoin "has posted three consecutive months of price gains for the first time since 2012".
