Huobi Token, the token tied to the Huobi cryptocurrency exchange, experienced a flash crash in which the token price tumbled 90% from $4.60 to around $0.31 within about a ten-minute span. HT does not have a ton of liquidity, and so Huobi-linked executive Justin Sun reported that a "few users trigger[ed] a cascade of forced liquidations in the spot and HT contract markets".
Sun also announced that he had transferred $100 million to Huobi to provide more liquidity. He also announced that "Huobi will bear all leverage-through position losses on the platform resulted from this market volatility event of HT."
Although the token recovered quickly, the flash crash sparked rumors that Huobi was insolvent.
