@CryptoJelleNL
An entrepreneur-turned-cycle-investor whose whole method is one idea: bear markets run longer and deeper than anyone wants them to, so buy them slowly. That framework makes him easy to grade — and in 2026 it graded badly first and well second. He spent the spring arguing Bitcoin had much further to fall. It did not. Then he flipped bullish in mid-July, within days of the turn, and that one landed. In late September he went further: a new bull market, and his accumulation about 70% complete.
In short. Crypto Jelle posts dated Bitcoin analysis to @CryptoJelleNL and sells the reasoning behind it on a paid Slice page. The method is historical-analogue work — prior bear depths, Fibonacci retracements, weekly RSI, range reclaims — applied to a dollar-cost-averaging plan rather than to trades. On our rolling 2026 sample of nine posts the record is 4 played out, 2 open, 3 went against, and the halves are not interchangeable. His spring bear thesis missed: on 11 March he argued the market was underestimating how painful bears get, citing −77% and −84% analogues; Bitcoin instead rallied +17.4% to $82,018 and its deepest print since is $58,566, about −53.5% from the $126,080 peak he cited. On 30 March he put the bottom below the 0.618 retracement — the press read that as sub-$57,000 — and it never got there. His July reversal worked: on 16 July he called the range-low reclaim a “big win for the bulls” and on 21 July put 70k on the board; Bitcoin cleared 70k on 21 August and was +33.8% at its 22 September high. September was mixed: on 17 September he said the market “isn't ready to push higher yet”, five days before Bitcoin ran +13.7%; his 18 September NEAR call ran +71.2%; and on 21 September he declared “the new bull market is here”. He is now openly bullish.
The only biography in his own words that we could fetch from a live primary source is his CoinMarketCap Academy author page: “Jelle is an entrepreneur with a wide range of interests. Although primarily focussed on growing and building businesses, he got hooked on financial markets at a young age. Since 2020, he shares his thoughts and ideas on Twitter, and now on Alexandria too. Jelle is currently DCA-ing back into Bitcoin and Ethereum.” Read it as history rather than as a current CV: the same page states that he is no longer affiliated with CoinMarketCap, and it carries no date.
A lot of what circulates about him does not survive checking, so this page does not repeat it. There is no verified legal name — X shows only “Jelle”. There is no verified country: the handle ends in NL and secondary write-ups call him Dutch, but no primary source we fetched states one, so the page stops at the handle. There is no follower figure here either — X's syndication endpoint does not return one, its profile endpoint answers HTTP 402 from our host, and the secondary numbers disagree (one search summary says 115,200; this site's own registry estimates ~200,000). What the X endpoint does confirm: account id 787634466, display name “Jelle”, blue-verified, and no affiliation badge — so there is no parent media organisation behind the account.
Since 11 November 2025 he has run a paid page on Slice, where the fuller version of the DCA reasoning lives. He advertises it on X himself, with a discount code, which is why it is disclosed in the money section below rather than buried. His own framing there is narrower than the label suggests: “This is not a signals group, but a place to learn more about how I trade and why. Don't ask for personalised trading advice, you're responsible for your own trades.” On 2 October the page displayed a 73% win rate and 39% ROI — self-reported, unaudited numbers on his own sales page, and not the ones on this dossier.

Analogue-driven, position-led. Jelle does not trade the candle; he argues about where the cycle is and then buys on a schedule. The toolkit is historical comparison first — how deep the 2018 and 2022 bears went, how long each phase lasted, where prior lows sat relative to the 0.618 retracement, what weekly RSI did at each bottom — with range structure (range lows reclaimed, weekly resistance) as the near-term overlay. The strength of that is patience and a plan that survives a bad week; he was buying through the whole 2026 drawdown and says so with dates. The weakness is the flip side: an analogue is a prior, not evidence, and when the current cycle refused to be as deep as the last two his framework kept him bearish through a 24% rally before the range work pulled him back.
Openly bullish since 21 September: he calls it a new bull market, says his accumulation is about 70% complete and is waiting to buy dips. Before that he was cautious for most of 2026 and willing to hold a bearish view for months — so read the current stance as a recent turn, not a constant.
Nine dated posts from @CryptoJelleNL, each captured verbatim and charted against real price. The tally is 4 played out, 2 open, 3 went against, and the sequence tells you more than the score. The two that went against are a single spring thesis, held through March: Bitcoin was going to fall a lot further, to somewhere below the 0.618 retracement — sub-$57,000, as NewsBTC read it. From the 30 March post Bitcoin instead ran +24.4% to $82,018, and when the drawdown finally came it stopped at $58,566 on 1 July — 2.7% above the level, and no deeper than the −53% he had already dismissed as shallow. Then he turned. On 16 July he called the range-low reclaim a “big win for the bulls” and on 21 July put 70k on the board; Bitcoin tagged $73,021 on 21 August and $86,597 on 22 September, +32.8%. September repeated the pattern in miniature: a slow-bleed call on 17 September that Bitcoin answered with +13.7% in five days, a NEAR continuation call the next day that ran +71.2%, and the 31 August breakout condition met on 21 September. The two open calls are the current stance: a 14 September buy, and a new bull market declared.
“The new bull market is here.”
The trigger for the 31 August card, called in his own words. Earlier that morning, after adding on the breakout, he had posted “Now roughly 45% into the market”; on 28 September, after the weekly close he had asked for, he put his accumulation at “about 70% complete”. From $81,169 Bitcoin ran +6.7% to $86,597 on 22 September and holds $85,208, +5.0%. A new bull market is a claim about years, not days, so this stays open.
𝕏 Post“Key resistance shattered, and the ATH-anchored VWAP has been broken as well.” — @CryptoJelleNL on X↗ x.com“if $NEAR closes the week like this, I think there's a lot more fuel in the tank for upside.”
A conditional with a clear trigger, and the trigger fired. He posted on a Friday with NEAR at $3.15, already more than double the $1.52 entry he said he had missed — so this was a call on continuation, not on a bottom. The week closed higher ($4.16 on the 21 September mark) and NEAR ran +71.2% to $5.39 on 28 September; it holds $4.87, +54.7%. Played out. He did not say in the post whether he bought, so read this as a call, not a trade.
𝕏 Post“Missed my $1.52 entry by a hair…” — @CryptoJelleNL on X↗ x.com“Tells me the market isn't ready to push higher yet.”
The bearish read he held through mid-September, argued with data: ~750m in ETF outflows in two days, coins leaving exchanges, treasuries no longer buying. The evening before, he had said he was “betting on that slowbleed scenario” until the range was reclaimed, and that morning he had laddered bids between 70k and 65k. Neither came. From $76,147 Bitcoin ran +13.7% to $86,597 on 22 September, five days later, and holds $85,208, +11.9%. Went against. To his credit he turned fast: on 18 September he posted that the bulls had reclaimed the range lows, and on the 21st he called the new bull market (above).
𝕏 Post“The demand wave that pushed $BTC to $80k is drying up.” — @CryptoJelleNL on X↗ x.com“I don't care about short-term volatility; I'm simply playing the long-term game.”
Not a forecast — a position, posted with a date, which is the most checkable thing an accumulator does. He bought at $76,819. Bitcoin dipped to $75,590 (−1.6%) two days later, then ran +12.7% to $86,597 on 22 September and holds $85,208, +10.9% above his buy. A good fill so far, but the stated horizon is the cycle, so this stays open. Coinspeaker embedded the post the same day; note that the “$5k jump and we're in a bull market” framing in that article's headline is the outlet's, not his.
𝕏 Post“New week, same plan… I bought more $BTC today” — @CryptoJelleNL on X↗ x.com“Break it, and the new bull market kicks off.”
A conditional with the condition named — and this time it was met. Posted at $77,658, Bitcoin first pushed to $81,265 on 4 September and was turned back, sliding to $75,590 on 16 September (−2.7%), so the second half of the post, protecting two weeks of profit, was sound. Then it broke: $86,597 on 22 September, +11.5% from his post, and it holds $85,208, +9.7%. The post named no level; by 18 September he was naming $83k as the line that would flip weekly structure, and the 28 September weekly mark printed $84,449. He called the break himself on 21 September (card above). Played out on the break and the follow-through; the “new bull market” half is a multi-year claim and is not what is graded here.
𝕏 Post“Decision time for BTC. Right at key weekly resistance.” — @CryptoJelleNL on X↗ x.com“Eyes on those 70k range highs if so.”
The follow-up to 16 July, and the one that put a number on it: 65–67k was Q1 resistance he expected to cut through, with 70k the target beyond it. From $65,185 Bitcoin dipped −3.7% to $62,773 on 2 August, then cleared $70,000 on 21 August at $73,021 and ran to $86,597 on 22 September — +32.8% — and holds $85,208, +30.7%. The target was hit. Read it as the second leg of one bullish thesis, not a separate win.
𝕏 Post“$BTC reclaimed the range lows, and is now pushing higher — as expected.” — @CryptoJelleNL on X↗ x.com“Big win for the bulls, $BTC has reclaimed the previous range lows!”
His bullish flip, and the timing was good: 15 days after the 1 July low of $58,566, with most of the analysts quoted alongside him in the same article still calling for a flush to sub-$60,000. From $64,717 Bitcoin gave back only −3.0% ($62,773, 2 August) before running to $86,597 on 22 September — +33.8% — and holds $85,208, +31.7%. He hedged it properly too: a “good start” with “loads of levels to break”, summer is slow, “DCA, nothing more.”
SourceThe $65.5K Rejection: What Top Analysts Are Saying About Bitcoin's Next Move — CryptoPotato↗ cryptonews.net“$BTC's bear market lows have historically formed below the 0.618 retracement level.”
“Is this time different? Doubt it,” he concluded — and this time it was. NewsBTC put the level his post implied at below the $57,000 area. From $65,947 Bitcoin first went the other way, to $82,018 on 11 May (+24.4%), and when the drawdown finally came it bottomed at $58,566 on 1 July — −11.2%, and 2.7% above the $57,000 line. Bitcoin has since run to $86,597 (+31.3%) and holds $85,208, +29.2%. A near miss on the level, a clear miss on the trade: anyone who waited for sub-$57k to buy is still waiting, with Bitcoin 29.2% above where he said it.
𝕏 Post“$BTC's bear market lows have historically formed below the 0.618 retracement level.” — @CryptoJelleNL on X↗ x.com“I still think many people are underestimating bear markets and how painful they tend to be.”
The thesis was explicit: down 44% from the high with a −53% local bottom is shallow, because the previous two bears ended at −77% and −84% — roughly $29,000 and $20,200 against the $126,080 peak he cited. Neither arrived. From $69,849 Bitcoin rallied +17.4% to $82,018 by 11 May, and the eventual low of $58,566 on 1 July — −16.2% from his post — was −53.5% from that peak, the same shallow bear he was dismissing. Bitcoin has since run to $86,597 (+24.0%) and holds $85,208, +22.0% above where he posted. NewsBTC relayed the thesis on 15 March as “more pain ahead for BTC”. X truncated this post; we grade only the text it returned.
𝕏 Post“I still think many people are underestimating bear markets” — @CryptoJelleNL on X↗ x.comOutcomes are our read of his stated lean against real price, not his own scoring — and not the 71% win rate his Slice page advertises, which is self-reported and measures something else entirely. Every quote is linked on its card and reproduced in full in the verified corpus, alongside six in-window posts we examined and excluded, each with its reason — including a dated $INJ call that was working for him but sits outside the four assets this site can price. The 11 March and 21 July cards are the second post of an evolving thesis in each direction, not independent wins or losses; they are charted because each adds a claim the other does not test. The same goes for 31 August and 21 September: the condition, and the post calling it met. For this update we read every post he made from 14 September to 1 October; the three added are the ones with a priceable claim in one of the four assets we chart. X truncates long posts at ~277 characters and the 11 March post is truncated: we quote and grade only the text X returned. Prices are CoinGecko daily marks. Near-term marks can flip as the cycle resolves.
There is a paywall here and he points at it himself, and since mid-September there are labelled exchange ads too, which makes this section short and factual rather than speculative. The thing to understand is the direction of the incentive: the free posts are the shop window, and the reasoning behind them is the product.
Since 11 November 2025 he has sold a subscription on Slice, promoted on X with the code JELLE50 for half off a first month. Most of the feed there is marked private. His own description: “This is not a signals group, but a place to learn more about how I trade and why.” On X on 30 September he pitched it as “Transparently sharing every entry and exit live on @SliceApp”, with weekly updates and Q&A.
On 2 October the Slice page displayed a 73% win rate and 39% ROI across 99 posts (71%, 33% and 91 on 15 September). Those are platform-displayed, self-reported and unaudited figures on a sales page, with no published methodology. They are not the numbers on this dossier — ours come from CoinGecko price against dated public posts, and they read 4 / 2 / 3.
He wrote for CoinMarketCap Academy, which now states he is no longer affiliated. His X posts are regularly picked up by NewsBTC, CryptoPotato and Coinspeaker, which is free distribution for the paid page.
Since at least 16 September he has posted OKX promotions labelled as ads on X with a referral link in his name — for EU perpetual futures “with up to 50x leverage” on 16 September, and for OKX Shield on 23 and 30 September. He labels them, which is right; it is still a paid relationship with an exchange. He has also twice promoted @ensembleio, a tokenised-leverage project, without an ad label; we found no stated relationship either way. No token of his own and no affiliation badge on the X account. He holds what he talks about — he posts the days he buys, and on 17 September said “a big portion of my net worth is in the stock market” — which is disclosure, and also a position.

There is no video library to link. Crypto Jelle publishes on X and behind a paid Slice page — no podcast and no YouTube channel we could confirm is his. That is exactly why every call above is a timestamped post rather than a clip: X's own syndication endpoint returns the author, the text and the UTC date, which is a harder record to argue with than a transcript. The full corpus — including the six in-window posts we examined and excluded, with the reason for each — is cited on every card.
A crypto investor who posts dated Bitcoin analysis as @CryptoJelleNL on X and sells the reasoning behind it on a paid Slice page. His CoinMarketCap Academy bio describes him as “an entrepreneur with a wide range of interests” who has shared market ideas publicly since 2020. His real name, country and follower count are not verifiable from any primary source, so this page does not state them.
On our rolling sample of nine dated 2026 posts: four played out, two are still open, three went against. The pattern matters more than the tally. His spring bear thesis — that Bitcoin would fall far deeper, below the 0.618 retracement and roughly sub-$57,000 — did not happen; Bitcoin bottomed at $58,566 and rallied. His mid-July flip did: he called the range-low reclaim on 16 July, 15 days after the low, and the 70k target he named on 21 July was tagged on 21 August. September was mixed: a slow-bleed call on 17 September went against within five days, while his 18 September NEAR call ran +71.2% and the breakout he had conditioned on 31 August arrived on 21 September.
Cycle analogues applied to a dollar-cost-averaging plan. He compares the current drawdown to prior bear markets on depth and duration, uses Fibonacci retracements and weekly RSI to argue where a bottom should form, and watches range reclaims for the near-term. He buys on a schedule rather than trading, and posts the days he buys.
The posts charted on this page were all free on X, but yes — he runs a paid subscription on Slice, promoted with the code JELLE50, and most of that feed is private. He describes it as a place to see how and why he trades rather than a signals group.
Not publicly known, and no credible figure exists. His Slice page advertised a 73% win rate and 39% ROI on 2 October, but those are self-reported, unaudited numbers on his own sales page and say nothing about net worth. Ignore any specific figure attached to his name.
