Here's what happened:
(1) AMM holders sent AMM to HitBTC to sell.
(2) An error in the HitBTC system created millions of counterfeit "fake" AMM tokens that were injected into the market.
(3) Market was flooded with millions of fake AMM tokens.
(4) HitBTC accused those who unknowingly bought their fake counterfeit tokens of fraud, even though they left the counterfeit token market open for a full day collecting transaction fees.
HitBTC made millions of counterfeit AMM tokens, they collected transaction fees on these illegal trades, and left the illegal market open for hours after they knew the tokens were fake.
HitBTC. Refund. Now.
