The huojian exchange privately locked up everyone’s quantitative trading of cell currency funds and released them at a rate of one in 10,000 every day, making it impossible for everyone to withdraw the currency smoothly, causing a catastrophic blow to many investors.

Finally, the user's liquidity was seized, and the new quantitative funds were insufficient, causing a stalemate.
