@efebulduk
Turkish economist and founder of the WinningCircle trading academy, with about 450,000 followers on X. On 1 October 2026, with Bitcoin at $83,576, Bulduk answered a follower: “Bence düşecek.” The post says: I think it will fall. Bitcoin first rose to $86,490 on 5 October and then fell to $73,721 on 11 November. Two weeks before that post, on 19 September, Bulduk had expected a pullback that did not come for five weeks.
In short. Efe Bulduk comments on crypto, stocks and US politics in Turkish, on X and in live broadcasts. On five dated Bitcoin calls from September to November 2026, the record is 1 played out, 3 open, 1 went against. The 1 October call for a fall played out. The 19 September call for a pullback came just before a rise to $86,597. On 10 November, with Bitcoin near $73,721, Bulduk wrote that one more sell-off would come by the end of January and that it would be the last low.
Efe Bulduk posts on X as @efebulduk. The account was opened in December 2018 and has about 450,000 followers. The YouTube channel has 101,000 subscribers. A Substack profile under the same name reads “Economist and founder of Winning Circle Trading Academy”. WinningCircle posts on X as @WinC300, and Bulduk calls its members students. The X profile gives Paris, France as the location, while the posts in our sample describe life and events in Türkiye. Bulduk writes in Turkish. Quotes on this page are the Turkish originals, and the summaries give our own translation. We found no public statement of pronouns, so this page uses the name.
How the sample was built: X returned 207 of the account's own posts from 17 April to 12 November 2026. Of these, 68 are not replies. Most of them announce live broadcasts or are about US politics, stocks such as SpaceX and Nvidia, and Bulduk's own trades. Only a few state where Bitcoin goes next. We chart each of those once, including one reply of 1 October in which the claim is stated plainly. Bulduk gives most market views in live broadcasts in Turkish, and we cannot read what is said in them. We found no ETH call in the sample. On 20 May Bulduk wrote of having been away from X for some time because of a family illness, and the sample has no Bitcoin call before August.
Posts we did not chart, and why. On 12 August, with Bitcoin at $63,538, Bulduk wrote that Bitcoin was undecided and weak while gold stayed strong. That is a description, not a forecast. Seven days later Bitcoin began a rise that reached $86,597 on 22 September. On 21 October, at $82,944, Bulduk reported large buyers in the Binance order book and warned people who were short on low time frames. The warning is about hours, and our data is daily. The next day's mark was $84,082 and the mark after that was $81,328. On 30 October Bulduk posted a chart with a drawn path for Bitcoin and the words “Bu grafik kenarda dursun.” The post says: keep this chart to one side. The path is a drawing with no claim in words, so it is not charted.
Older record, from press. On 6 February 2026 the Turkish finance site hisse.net reported a self-criticism by Bulduk after Bitcoin fell below $69,000. It quoted Bulduk: “Ben dahil herkesin yanıldığı bir kez daha tescillenmiş oldu”. The report says: it is confirmed once more that everyone was wrong, me included. The same report said Bulduk expected a low between $52,000 and $58,000, with April as the month. That date is before our price window, so it is not charted. In our window the lowest daily mark is $58,566 on 1 July, three months after April and just above that range. In a reply of 30 September 2026 Bulduk also wrote of having lost 5.1 million dollars of personal money when the stablecoin UST collapsed, and of never having told anyone to buy Luna.

Order flow, levels and politics. Bulduk watches who is buying and selling: the Binance order book, the Coinbase price gap, futures against spot. The posts also follow US events closely, such as the CLARITY Act votes in the Senate and Federal Reserve meetings, and tie market moves to them. Price levels are given as conditions: if Bitcoin holds a level, Bulduk does one thing, and if it fails, another. Most of the detail is in the live broadcasts, and the posts are short notes around them.
Bearish for the next weeks, bullish after that. On 10 November Bulduk expected a small recovery and then a sell-off that could last until the end of January, and wrote of buying into that fall. In a reply the same day Bulduk wrote that Bitcoin bought in the 64,000 to 65,000 area, or at 58,000 to 59,000, would not disappoint over one year.
Five dated Bitcoin calls from Efe Bulduk (@efebulduk)'s own X posts, charted against real price. The tally is 1 played out, 3 open, 1 went against.
“Önümüzdeki günlerde Bitcoin fiyatının bir nebze toplamasını bekliyorum. $77-78k üstü denenebilir.”
Prices in this text as of 12 Nov 2026Charted at $75,267. The post went out at 20:50 UTC, when Bitcoin was at $73,817 on Binance, and the next day's mark was $73,721 (−2.1%). The post says: in the coming days I expect the Bitcoin price to recover a little, and a move above $77,000 to $78,000 can be tried. It goes on: after that I think a sell-off will come that could last until the end of January at the latest; this will be the last low for me, and I will be a buyer in that fall. Bulduk wrote that the first leg of the fall had already come. Bitcoin is at $73,733 (−2.0%). Open: neither the recovery nor the sell-off has been tested yet. The window runs to the end of January 2027.
𝕏 Post“Önümüzdeki günlerde Bitcoin fiyatının bir nebze toplamasını bekliyorum. $77-78k üstü denenebilir.” — Efe Bulduk (@efebulduk) on X↗ x.com“Fiyat yuvarlakla işaretli seviyeyi kırmaya çalışıyor. Kırarsa 1'e gidecek. Başarısız olursa 2'ye.”
Prices in this text as of 12 Nov 2026Charted at $77,385. The post went out at 17:42 UTC with a four-hour Bitcoin chart that showed the price at $80,210, and the next day's mark was $80,443 (+4.0%). The post says: the price is trying to break the level marked with a circle; if it breaks, it will go to 1; if it fails, to 2. On the chart the circle is on a rising line near $81,000. Line 1 is drawn at $84,944. Line 2 is a lower rising line, near $70,000 at the right edge of the chart. Bitcoin did not hold above the circled line. It fell to $76,006 (−1.8%) on 6 November and to $73,721 (−4.7%) on 11 November. It is at $73,733 (−4.7%). Open: the break failed, so the second path applies, and the price has not reached line 2.
𝕏 Post“Kırarsa 1'e gidecek. Başarısız olursa 2'ye.” — Efe Bulduk (@efebulduk) on X↗ x.com“Böyle hareketler büyük hareketler arifesinde olur. Görünen o ki biraz daha acı çekilecek”
Prices in this text as of 12 Nov 2026Charted at $81,274. The post went out at 21:09 UTC, after most of that day's fall: Bitcoin was at $79,175 on Binance, and the next day's mark was $77,839 (−4.2%). Fourteen minutes earlier Bulduk had written that an exchange had been hacked and that Coinbase was selling hard. The post says: moves like this happen on the eve of big moves; it looks like there will be a little more pain. It goes on to say that very large gains will follow, and it lists futures for US investors, tokenized stocks, relief after the election and more liquidity. It ends “Oyunun içinde kalmaya bakın”. The post says: try to stay in the game. From the 30 October mark Bitcoin rose to $80,443 on 5 November and then fell to $73,721 (−5.3%) on 11 November. It is at $73,733 (−9.3% from the charted mark). Open: more pain came, and the gains have not.
𝕏 Post“Görünen o ki biraz daha acı çekilecek” — Efe Bulduk (@efebulduk) on X↗ x.com“Bitcoin'de yoğun yapay fiyat hareketi gözlemliyorum. Bence düşecek.”
Prices in this text as of 12 Nov 2026Charted at $83,576. This is a reply to a follower, sent at 20:14 UTC, when Bitcoin was at $84,786 on Binance. The next day's mark was $84,842. The post says: I see heavy artificial price movement in Bitcoin; I think it will fall. Twelve minutes later, in a second reply, Bulduk gave a test: a daily close below 83k should raise the doubt that Efe may be right, and two daily closes more so. Bitcoin first rose to $86,490 (+3.5%) on 5 October. The first mark below 83k came on 9 October at $81,686 (−2.3%), and the second on 10 October. Bitcoin fell to $73,721 (−11.8%) on 11 November and is at $73,733 (−11.8%). Played out: the fall came, after a rise of a few days.
𝕏 Post“Bitcoin'de yoğun yapay fiyat hareketi gözlemliyorum. Bence düşecek.” — Efe Bulduk (@efebulduk) on X↗ x.com“Piyasa Çarşamba gününe kadar kuvvetli kalmaya, Bitcoin'de $79k üstü kapatmaya devam ederse kripto varlıkların portföyümdeki ağırlığını arttıracağım.”
Prices in this text as of 12 Nov 2026Charted at $80,874. The post went out at 14:37 UTC, when Bitcoin was at $81,510 on Binance. Bulduk wrote of being careful about the rise, of holding a short position in one altcoin, and added “bu seviyelerden geri çekilme bekliyorum.” The post says: I expect a pullback from these levels. The quoted line says: if the market stays strong until Wednesday and Bitcoin keeps closing above $79k, I will raise the weight of crypto in my portfolio. The pullback did not come. Every daily mark to Wednesday 23 September was above $79,000, and Bitcoin rose to $86,597 (+7.1%) on 22 September. So Bulduk's own rule pointed to buying more near $86,183, the mark of 23 September. Bitcoin stayed above the price of the post until late October. It is at $73,733 (−8.8%), which is −14.4% from the 23 September mark. Went against: the price rose in the days the post was about, and the rule said to add near the high.
𝕏 Post“bu seviyelerden geri çekilme bekliyorum.” — Efe Bulduk (@efebulduk) on X↗ x.comOutcomes are our read of the stated claim against real price, not Bulduk's own scoring. Quotes are the Turkish originals; the summaries give our own translation. Selection: from 207 own posts between 17 April and 12 November 2026, as returned by X, we chart every post that states where Bitcoin goes next, once. Each call is charted at that day's midnight CoinGecko mark. Bulduk posts in the afternoon and evening UTC, so the chart can include a move that happened before the post. Each card gives the Binance price at the minute of the post and the next day's mark, and we grade from those. The 29 October post says crypto and does not name Bitcoin; we chart it against Bitcoin, the largest coin. The 4 November post names no coin in its text; the attached chart is Bitcoin against the dollar. The $1,000 line on each card assumes buying on the day. On the bearish cards it shows what a buyer would have lost, not what Bulduk said to do.
Efe Bulduk runs a trading academy, does sponsored content and trades in public. Here is what we found.
Bulduk is the founder of WinningCircle, a trading education business. On 30 October 2026 Bulduk wrote that the first 48 videos of the WinningCircle course were being opened for free. We did not find the price of the rest of the course.
Some posts carry the Turkish tag for a paid partnership, #isbirligi. On 30 April 2026 Bulduk wrote that a podcast series about well-known companies is published in partnership with Midas, an investing app. A 10 July post from an event with the chief executive of Circle carries the same tag.
Since October 2026 Bulduk shows trades on a WinningCircle page called Canlı Cüzdan, which means live wallet. On 12 November Bulduk reported 28 winning trades out of 28 in 36 days and a return of 21.5% in dollars. In a reply the same day Bulduk wrote that the account started with $30,000. These are Bulduk's own figures, and we have not audited them. Bulduk wrote on 6 November that following the trades costs nothing and that the programme has no sponsor.
The channel has 101,000 subscribers. A channel of that size can earn from ads, and we did not find figures for it.
In a reply of 30 September 2026 Bulduk wrote of losing 5.1 million dollars when the stablecoin UST collapsed.

A Turkish economist and the founder of the WinningCircle trading academy. Bulduk posts in Turkish on X as @efebulduk to about 450,000 followers and has a YouTube channel with 101,000 subscribers.
On 10 November 2026 Bulduk wrote that Bitcoin could first recover to above $77,000 to $78,000, and that a sell-off would then come by the end of January 2027 at the latest. Bulduk called that fall the last low and wrote of buying into it. No price was given for the low.
On our sample of five dated Bitcoin calls from September to November 2026: one played out, three are open and one went against. The 1 October call that Bitcoin would fall played out, and Bitcoin is 11.8% lower since. The 19 September call for a pullback went against, because Bitcoin rose 7.1% in the next three days.
From the WinningCircle trading academy, from sponsored content marked as paid partnerships, from a YouTube channel and from trading. Bulduk shows trades on a public page and reports the results there. We have not audited those results.
