You may think that the existence of information asymmetric is bad for decision making and bad for market-making (in terms of liquidity), but the truth is quite the opposite. 

According to “The blockchain, plums, and lemons: Information asymmetries & transparency in decentralized markets”(Notheisen, Benedikt; Weinhardt, Christof, 2019), blockchain technology has significantly increased transparency, but at the same time, the transparent market attracted more 'bad acts/bad actors', then makes the market unattractive to other participants, resulting generations of not interested in the market, less future newcomers until the game collapse. 

This issue seems kinda like the macro-level of MEV extraction, really interesting when you related these findings to the Warpcast ongoing debate about the spammy issue.
