Even though that the amount to be sold isn't that much compared to what Grayscale has sold off, I still feel that the market will definitely react to it, except if the sales occur in batches but no one knows which method that the US government is going to use to liquidate this number of Bitcoin (2.9k) worth $118M Bitcoin but should they sell at once, this will in the short term may put pressure on the price of Bitcoin to see new lows from the last price 38.5k we just bounced from maybe push down the price towards $31k, but the sell will immediately be absorbed by the Bulls immediately we tap into that support.
As Husires said above, the total trading volume of bitcoin in 24 hours is 531,375 BTC and with only 2k9BTC sold, are you very concerned that bitcoin will drop to $38k or even $31k? You are underestimating this market and overestimating the US government.
In the past 10 days since the ETFs were approved, Grayscale and FTX have taken turns selling billions of dollars worth of bitcoin to the market, but that only caused bitcoin to drop to $38k. Meanwhile, the US government holds just over $118 million worth of bitcoin, which is unlikely to cause more selling pressure than Grayscale has done in recent days.
Personally, I think there will be no impact on the market and no one cares about this.
