- Who is he: An Austrian doctor turned cryptocurrency entrepreneur, author, and YouTuber who built his fortune and fame on Bitcoin via TenX and Cake DeFi (later known as Bake).
- What did he do: In early 2025, he exited most of his cryptocurrency holdings, even shorted Bitcoin, and switched to the Nasdaq-100 ETF (QQQ).
- Where he stands now: One of the most vocal Bitcoin skeptics in the German-speaking world, calling cryptocurrencies “pure speculation.”
- Why are critics angry? They say a guy who got rich on bitcoin and once promoted it as a lifelong asset is now fearmongering against it for personal gain — and they point to his history with TenX, the financial watchdog BaFin investigation, and the collapse of DeFiChain.
- Why supporters defend it: They say he simply changed his mind with new information and reallocated his portfolio — which is exactly what good investors do.
Who is Julian Hosp?
Julian Hoss is an Austrian doctor who became a cryptocurrency entrepreneur, best-selling author, and YouTube personality after buying Bitcoin early. He is one of the most well-known – and polarizing – figures in the German-speaking cryptocurrency scene. A former windsurfer, he has reinvented himself around the goal of making people “crypto friendly,” publishing widely read books and building a large following across YouTube and X.
This contract itself has been surrounded by recurring controversy. The name HOSP is associated with a series of high-profile projects that generated enormous interest, and caused painful losses for many investors.

- Current role: Bitcoin Skeptic, Content Creator, Paid Education (“Inner Circle”)
What are TenX, Cake DeFi, and DeFiChain?
TenX, DeFi (later Bake), and DeFiChain are the three cryptocurrency projects that define Julian Hosp’s track record – and all three ended in controversy or huge losses for investors. To understand the current debate, you have to understand this history.
- Tinex (2017): Hosp rose to prominence as co-founder and president of TenX, a cryptocurrency payment card project that raised about $80 million in an ICO in 2017. The product never achieved its ambitions, the card program faltered, and Hosp left in January 2019 after an internal dispute. Some industry critics have called it an exit scam — a characterization Hosp rejects.
- Davy Cake/Bake: After TenX, Hosp co-founded Cake (later renamed Bake) with U-Zyn Chua, providing staking, lending, and liquidity mining services. In January 2022, German financial regulator BaFin opened an investigation, saying the company was operating in Germany without the required license.
- Division (DFI): Blockchain associated with cakes/breads. Its token has collapsed dramatically from its peak in December 2021, leaving many holders deep underwater.
Cake’s chapter ended bitterly. Co-founder U-Zyn Chua filed to liquidate the company in late 2023 amid a shareholder dispute, and at the time made detailed allegations about the financial management and use of company funds — allegations that the Hosp team disputed. Bake was eventually sold to a subsidiary of GSTechnologies, and Hosp indicated that he would be stepping back from the cryptocurrency spotlight.
Hosp has long objected to the harshest framings of these events, attributing failures to market conditions, partners, or broader industry turmoil rather than any wrongdoing of his own.
Why is Julian Hoss so controversial now?
The current controversy stems from Julian Hosp’s decision in early 2025 to exit cryptocurrencies, short sell Bitcoin, and move into stocks (QQQ) — after years of promoting Bitcoin as a transformative asset. Flashpoint is not a failed project; It’s the axis itself.
In early 2025, Hosp announced that it exited most of its cryptocurrency positions, at one point shorted it, and moved into other asset classes, notably the Nasdaq-100 ETF (QQQ). He framed cryptocurrencies as having less and less use in the real world and called them “pure speculation.”
Since then, he has become one of the most vocal Bitcoin skeptics in the German language. Throughout 2025 and into 2026, he repeatedly warned of more significant declines — at various points floating scenarios of a Bitcoin price decline toward $20,000-$30,000 or even lower — while citing structural concerns such as weak institutional demand, the risks of quantum computing, and over-reliance on a handful of large buyers such as Michael Saylor’s strategy. He also stated that since selling near the end of January 2025, his QQQ-led portfolio has outperformed Bitcoin with lower volatility and better risk-adjusted ratios.
For a man who built his fortune and fame on Bitcoin, this reversal is exactly what lit the fuse.
What do people actually say?
The dispute has played out publicly on The exchange picks up both camps cleanly.
The critic, as published mgp.ethsummed up the discontent felt by many long-time followers. Paraphrasing: Hoss went from windsurfer and doctor to cryptocurrency millionaire because he bought Bitcoin early and built TenX and Cake with it — and without Bitcoin he “would probably still be an accident surgeon in Innsbruck.” Instead of gratitude, the critic says, Hoss now drops Bitcoin in almost every video, scares people, and plays the role of “concerned warninger.” The charge: This is not critical thinking, it is ingratitude and hypocrisy – and someone who would remain a nobody without Bitcoin should not spoil the entry of those who are still trying to enter.
Is Julian Hoss a scam or a smart investor? Two ways to read it
- There is no consensus: some see Hosp as a smart investor who has legitimately turned away from cryptocurrencies, while others see narcissistic, self-serving behavior given his history. Reasonable people land on opposite sides.
- The “he did nothing wrong” point of view. In this reading, Hosp did what every investor is supposed to do: spotted an opportunity early, capitalized, and reallocated when his thesis changed. Selling an asset and moving to something you believe is better is not betrayal, it is portfolio management. He says he was transparent about both buying and selling, publicly and in real time. Being early with Bitcoin and then wary of it later is not a contradiction; It’s an evolving point of view. No one is obligated to stay loyal to an asset forever, and changing your mind with new information is a feature of good investing, not a character flaw.
- The “narcissistic and harmful” outlook. The opposition camp sees something more troubling. To these critics, Hosp spent years promoting Bitcoin as a semi-permanent, life-changing asset, built companies and a personal brand on that promise, and enriched himself — and then turned around to publicly disparage the very thing he created, in ways they see as fear-mongering aimed at selling his own products and webinars. Above is its history: TenX, the BaFin investigation, the Cake/DeFiChain collapse and the legal battle. For investors who lost money after his previous enthusiasm, the pivot is seen as self-serving, arrogant and unprincipled. The tone he uses in his rebuttals – describing critics as “socialists” and “whiners” – reinforces this perception for them.
What’s the takeaway on Julian Mania?
Whether Julian Hosp was a smart investor who timed his exit or a polarizing figure who took advantage and then moved up the ladder depends on how much weight you give to his track record versus his returns. His story falls on a fault line that runs through the entire cryptocurrency world: the gap between condemnation and salesmanship, between changing your mind and abandoning the people who believed you.
What’s not in dispute is that he remains one of the most watched voices in the space — and that his Bitcoin skepticism, right or wrong, will continue to generate controversy as long as he continues to post.
