FCoin Declares Itself Insolvent, Reveals $130 Million Shortfall in BitcoinAuthor: Sherlock GomesLast Updated: 12 June 2020 Cryptocurrency exchanges FCoin recently declared that it is insolvent and reported a shortage of cryptocurrency assets of up to $130 million. The exchange has withdrawn all trading and withdrawals for users.Controversial exchange downFCoin followed a very controversial “trans-fee mining” model. The exchange began in May 2018 when former Huobi CTO Zhang Jian introduced a new exchange model. Its new mining model would incentivize trading on the platform via their token called FT. The platform didn’t conduct an ICO for its coin. Instead, it gave away 51% supply of the coin to the people for making transactions. This meant that whatever amount of fee a user paid in BTC or ETH would get credited back into their account in the form of FT coins.The exchange also said that it would distribute 80% of the transaction fee is collected via BTC and ETH to the users. The idea of trans-fee mining was initially discarded but some exchanges took it up to see a rising daily trading volume.On Monday, Jiang wrote a long post discussing the ongoing circumstances of the company. He said that the exchange will not be able to process the withdrawal demands of the users because its asset reserve is now lower than its liability. It is anywhere between 7,000 to 13,000 Bitcoins short of its liabilities.Note that FCoin was one of the largest exchanges by trading volume at one time. However, the latest news of insolvency is putting several users in China in jeopardy as their assets are locked into the platform.Exit scam accusationsBinance CEO Changpeng Zhao also tweeted about the issue. He wrote,“I rarely called out anyone, with exceptions. On Chinese social media, I called FCoin a pyramid scheme in mid-2018. Their founder call his own plan a “better invention than Bitcoin”. That did it for me. Who would say such a thing? About themselves? except scammers.Zhang said that the exchange was not hacked and it is not an exit scam. He said that he finds the problems too complicated to explain in just one sentence. He said that the problem is actually because of some internal system errors. He said that these issues led to more transaction-based mining rewards being deposited in user accounts than what they should have rightly received. The company could not spot the problem with them soon enough because of which the gap kept growing throughout 2019.
