Using a specially constructed trading cage, the rodent gained widespread internet attention for his ability to consistently outperform human investors. The rodent died on Tuesday.
The hamster's death was announced on the official Twitter account of the furry financier, who has 18,000 followers on social media.
In an interview with the BBC, his owners said that he had "proved to us that the internet does not necessarily have to be a toxic wasteland."
"We have been completely overwhelmed by the countless and heartfelt condolences that we have received across all communication channels.
It is important to note that the lessons we personally gained from this project had little to do with cryptocurrency."
The hamster's financial success and subsequent fame were the results of an experiment conducted by two friends in Germany who wanted to demonstrate the randomness of success in the digital currency industry by using the hamster as a test subject.
On a Twitch Livestream, thousands of people tuned in to see Mr Goxx's trading office, which was attached to his regular cage. His decision-making process was well-known, and it involved spinning his "intention wheel" to select which cryptocurrency he wanted to trade and then entering either a buy or sell tunnel on his "office floor."
The electronics wired to his office completed the trade every time he ran through a tunnel, allowing Mr. Goxx to conduct his business as he desired.
On June 12 in the year 2021, the teeny-tiny trader began his financial career.
After his final day of trading on November 22, his portfolio had increased by 19.7 percent, resulting in a profit of approximately 98 Euros.
According to recent calculations by crypto-news site Protos, the hamster's most recent financial results outperformed those of Warren Buffet's Berkshire Hathaway, the world's largest investment company.
Mr. Goxx has even come out slightly ahead of Bitcoin, the most valuable of the crypto-currencies, on a few occasions.
Goxx Capital, on the other hand, was not a legitimate investment firm, and Mr. Goxx's human partners made it clear with every tweet that the hamster's decisions should not be construed as investment recommendations.
Mr. Goxx was viewed as the face of a "light-hearted side project" by the pair, who were both programmers and lecturers.
"It appears that most people from our generation see no other option than to invest a significant portion of their savings in the cryptocurrency market, despite having no understanding of what is going on there," the anonymous duo behind Mr. Goxx explained in September.
In an interview with the BBC, they explained that they were "joking about whether my hamster would be able to make smarter investment decisions than we humans."
Many people from all over the world have paid tribute to the much-loved hamster since the announcement of his death. His contributions to the crypto community have garnered hundreds of comments.
