Sylwester Suszek was born in 1989 in Katowice, Poland, and became a prominent figure in the media, particularly known as the "Polish King of Bitcoins." He was married and had a son. Suszek pursued higher education at Jagiellonian University, where he earned a bachelor's degree in business and project management. His interest in cryptocurrencies began during the early stages of their emergence, positioning him as one of the pioneers in Poland's digital currency landscape.
Raised in Piekary Śląskie, a city in the Silesian region, Suszek demonstrated entrepreneurial spirit from an early age. His first business venture was a computer store, which laid the foundation for his future endeavors in technology and finance. From 2011 onward, he managed Multimoney, a company specializing in providing credit solutions for small and medium-sized enterprises. This experience in financial services proved invaluable for his later ventures. Subsequently, he worked as the marketing director at Doradcy24, further honing his business acumen. At Lemon Finance, he served as CEO, focusing on financial intermediation services. The capital accumulated from these various business ventures provided the financial foundation necessary to launch his most ambitious project: a major cryptocurrency exchange platform.
Suszek's journey into the cryptocurrency world began with Bitcoin mining operations. In 2018, he proudly stated that one of his mining facilities in Katowice was producing 192 Ethereum (ETH) tokens daily, demonstrating the scale of his operations and his deep involvement in the blockchain ecosystem.
BitBay officially commenced operations on March 29, 2014. The exchange was co-founded by Suszek alongside Mateusz Bajer and Jacek Rogóż, forming a partnership that would revolutionize cryptocurrency trading in Poland. The platform distinguished itself through an innovative commission model based on users' monthly transaction volumes, making it more competitive compared to other exchanges at the time. Initially, the platform offered trading services for Bitcoin (BTC) and Litecoin (LTC), with exchange options for Polish złoty and euros, catering primarily to the Central European market.
The exchange experienced remarkable growth over the following years. In May 2018, Suszek announced a strategic decision to relocate the company's headquarters to Malta, a jurisdiction known for its cryptocurrency-friendly regulatory environment. At its peak, BitBay achieved a valuation of approximately 1 billion dollars, serving nearly one million registered clients and processing monthly trading volumes of around 20 billion dollars. This success established the platform as one of the leading cryptocurrency exchanges in the European market.
In 2020, the exchange found itself at the center of significant controversy following an investigative report by TVN, a major Polish television network. The report suggested that the funds used to establish the exchange may have originated from criminal activities. Suszek vehemently denied these allegations, maintaining that all capital came from legitimate business sources. This controversy raised questions about the origins of funding in the cryptocurrency industry and highlighted the challenges faced by crypto entrepreneurs in establishing credibility.
A significant transition occurred in 2021 when, after securing investment from a United States-based investor in May, Sylwester Suszek stepped down from his position as CEO. In November of the same year, the company announced a comprehensive rebranding initiative: the exchange changed its name from BitBay to Zonda, marking a new chapter in the platform's evolution. Przemysław Kral was appointed as the new CEO, taking over leadership responsibilities and steering the company in a new direction. This transition represented both an attempt to distance the brand from past controversies and to align with international expansion strategies.
By the age of 30, Suszek had accumulated substantial wealth through his various ventures in the cryptocurrency and financial services sectors. He purchased a luxury apartment in the prestigious "Żagiel" (Sail) building on Złota 44 in Warsaw, one of the most exclusive residential addresses in Poland's capital. His lifestyle reflected his financial success, with a notable passion for high-performance automobiles and the ownership of a private helicopter, which he used for both business and personal travel.
Suszek harbored ambitious investment plans that extended beyond the cryptocurrency sector. Among his projects was the proposed construction of Suszek Tower in Katowice, which would have been a landmark building in his hometown. Additionally, he explored real estate investment opportunities across multiple countries, diversifying his portfolio beyond digital assets. These plans demonstrated his vision for building a lasting business empire that would extend well beyond the volatile cryptocurrency market.
On March 10, 2022, Sylwester Suszek traveled to Czeladź, a small town in southern Poland, and has been missing since that date. His sudden disappearance sparked numerous theories and speculation within both the cryptocurrency community and the general public. Various hypotheses emerged regarding his fate: some suggested he may have fled to a tax haven to protect his assets, while darker scenarios linked his disappearance to criminal elements potentially connected to the cryptocurrency underworld or business disputes.
His family, particularly his sister Nicole, has continued searching for him with unwavering determination. Despite their efforts and public appeals for information, investigators working on the case have concluded that he is likely deceased, though no definitive evidence has been presented. The case remains officially open, and more than a year after his disappearance, police authorities continue their investigation, though progress has been limited. The mystery surrounding Suszek's fate has become one of the most intriguing unsolved cases in Poland's cryptocurrency community.
In November 2024, Nicole Suszek, the sister of the missing entrepreneur, reached out to Krzysztof Rutkowski, a well-known private detective in Poland, requesting his assistance in the investigation. Nicole has been openly critical of the police's handling of the case, expressing frustration with what she perceives as insufficient engagement and lack of progress in the official investigation. She has publicly stated her hope that Rutkowski's involvement might finally provide answers about her brother's fate and bring closure to the family. The decision to involve a private investigator reflects the family's determination to explore all possible avenues in their quest for truth, even years after Suszek's disappearance. This development has renewed public interest in the case and raised hopes that new information might emerge regarding the circumstances surrounding the disappearance of one of Poland's most prominent cryptocurrency figures.
