FCoin (cryptocurrency exchange)

FCoin was a cryptocurrency trading platform launched in May 2018 by Zhang Jian (reported as a former Huobi CTO). It became widely known for promoting a “transaction fee mining” (also described as “trans-fee mining”) model tied to its exchange token FT, under which users were effectively rebated fees in FT and fee revenue was shared with token holders.

In February 2020, FCoin paused trading and withdrawals after disclosing a major shortfall (reported as roughly 7,000–13,000 BTC, with some reporting framing this as up to about $130 million at the time), and reports described the exchange as insolvent. (coindesk.com)

The Twitter account @FCoinOfficial

The account at:

text https://twitter.com/FCoinOfficial

is presented (via third-party Twitter profile indexing) as “FCoin” and describes itself as:

• “The First Global Autonomous Digital Assets Trading Platform and Autonomous Organization for Future Community.” (twstalker.com)

Notes on identification / ambiguity

• The name “FCoin” has been used by multiple unrelated services and websites; therefore, the handle @FCoinOfficial should not be assumed to represent any particular entity solely from the shared name. (For example, there are separate “Fcoin Exchange” sites using other domains.) (fcoin.us.com)
• Because Twitter/X pages are often difficult to verify directly via automated text access, the description above is taken from a third-party index of the profile metadata rather than a direct page read. (twstalker.com)
