The profitability of sandwich bots on Ethereum has sharply declined, with average earnings dropping to just $3 per attack. Only six bots have managed to generate over $10,000 in total profit, highlighting the challenging environment for operators. Currently, about 30% of active bots are operating at a loss, while another third are barely breaking even. This intense competition and narrowing profit margins are pushing many operators out of the market, raising questions about the future viability of new entrants in this space.
