The lack of liquidity is what would push the price down, since demand is higher at lower prices.
Again, that's not how the US govt works with these things anyway (OTC auctions), so it is all a moot point.
We are talking about theoretically crashing the market, not an auction, and illiquidity won't protect it.
The last person who got that good of a deal was Tim Draper in 2014, which was a brilliant play and even then, I doubt he's sold it all.
