Who Is Julian Hosp? The Bitcoin Controversy Dividing the Crypto Community Explained

Who he is: Austrian doctor turned crypto entrepreneur, author, and YouTuber who built his wealth and fame on Bitcoin via TenX and Cake DeFi (later Bake). What he did: In early 2025 he exited most of his crypto holdings, even shorted Bitcoin, and rotated into the Nasdaq-100 ETF (QQQ). Where he stands now: One of the most vocal Bitcoin skeptics in the German-speaking world, calling crypto "pure speculation." Why critics are angry: They say someone who got rich on Bitcoin and once promoted it as a lifetime asset is now fear-mongering against it for personal gain — and point to his history with TenX, a BaFin investigation, and the DeFiChain collapse. Why supporters defend him: They say he simply changed his mind with new information and reallocated his portfolio — exactly what good investors do. Who Is Julian Hosp? Julian Hosp is an Austrian medical doctor who became a crypto entrepreneur, bestselling author, and YouTube personality after buying Bitcoin early. He is one of the most recognizable — and most polarizing — figures in the German-speaking crypto scene. A former competitive kitesurfer, he reinvented himself around the goal of making people "cryptofit," publishing widely-read books and building a large following across YouTube and X. That same decade has been shadowed by repeated controversy. Hosp's name is attached to a string of high-profile projects that generated enormous attention — and, for many of their investors, painful losses.

TenX, Cake DeFi (later Bake), and DeFiChain are the three crypto ventures that define Julian Hosp's track record — and all three ended in controversy or steep losses for investors. To understand the current debate, you have to understand this history. TenX (2017): Hosp rose to prominence as co-founder and president of TenX, a crypto payment-card project that raised around $80 million in a 2017 ICO. The product never delivered on its ambitions, the card program faltered, and Hosp departed in January 2019 after an internal dispute. Some industry critics labelled it an exit scam — a characterization Hosp rejects.
