Fcoin founder Zhang Jian may be hiding in the UK, involved in multiple projects such as Gridex and Jump.fun after fleeing.

In 2020, FCoin founder Zhang Jian admitted that 7,000-13,000 BTC (worth approximately $65 million to $120 million at the time) of user assets were unable to be redeemed, and the trading platform was indefinitely suspended. After that, Zhang Jian vanished without any public news.

According to a notable figure from a certain crypto dinner, he claimed to have met Zhang Jian in London last year, suggesting that Zhang Jian may be hiding in the UK. After his disappearance, he participated in the development of several projects as a co-founder, including various Heco projects that he allegedly took part in. He also co-founded the decentralized order book exchange Gridex, and the Ethereum ecosystem meme issuance platform http://jump.fun. However, projects like @GridexProtocol and @jumpdotfun quickly faced severe issues, causing significant harm to the community.

FCoin briefly achieved the highest trading volume globally through trading mining and voting for new listings, surpassing the total trading volume of the second to seventh largest trading platforms combined.

In the last moments before his flight, he released "The Truth of FCoin," mentioning, "Switching tracks to start over, compensating for losses with profits from new projects. Once the new project is on track, I will begin the long-term process of email withdrawals, which may take 1-3 years," but to this day, there has been no public and clear emergence of any project.
