Crypto Privacy Has Turned Into an Economic Crisis as MEV Bots Siphon Millions and Most Users Still Leak Everything

MEV bots are now burning more than half of gas on leading Ethereum layer‑2s while extracting tens of millions of dollars in profit, turning privacy from a philosophical concern into an economic crisis. Recent data shows roughly $24 million captured in a single month and estimates approach $1 billion annually across major chains. The Ethereum Foundation’s privacy roadmap highlights private reads as the most urgent gap, since exposed balances and positions fuel these attacks. Solutions such as encrypted mempools, trusted execution environments, and cheaper zero‑knowledge proving are emerging, but coordination and UX challenges remain.
