In the most recent update to the speculations regarding LUNA's market collapse, all parties concerned have openly denied any participation. Gemini, BlackRock, and Citadel are the corporations in question. The rumours began when comments on 4chan and Telegram accused the three corporations of market manipulation. Gemini was first to deny allegations on their Twitter account, followed by both BlackRock and Citadel denying the charges. "Rumours that BlackRock had a role in the collapse of UST are totally incorrect," stated BlackRock spokesperson Logan Kofflet. BlackRock, in reality, does not trade UST." Similarly, a Citadel spokesperson informed a trustworthy source, "Citadel Securities does not trade stablecoins, including UST."
The rumours started a few days ago, after the crypto market, particularly LUNA, plummeted in value. The claims originated with a 4chan post and quickly travelled to Twitter and Telegram. More gasoline was thrown to the fire when Charles Hoskinson shared the claims with his Twitter followers in a now-deleted post.
