When we talk about "most liquidated," we refer to something that has been sold or converted to cash quickly and easily. The antonyms for "most liquidated" would be words like "illiquid," "unmarketable," and "inconvertible." Something that is illiquid is difficult to sell or convert to cash quickly, while unmarketable refers to something that cannot easily find a buyer due to lack of demand. Inconvertible indicates that something cannot be turned into cash or another form of asset. Therefore, the opposite of "most liquidated" would be to describe something illiquid, unmarketable, or inconvertible, which would be challenging to sell or liquidate quickly.
