It's not clear whether Ulbricht has taken over control of these wallets, or if they are still being operated on his behalf. Either way, whoever does control the wallets made a big mistake when they tried to cash out on their memecoin stash by adding single-sided liquidity on Meteora. They accidentally initialized the liquidity pool at too low a price, allowing a MEV bot to snap up 5% of the token supply (notionally ~$1.5 million) at a discount and resell them.
The wallet operator then made the same error again with a larger quantity of tokens, selling off another 35% of the supply and losing out on around $10.5 million in notional value.
