Recently, looking at those "sandwich" and "arbitrage" screenshots on the blockchain, I feel both amused and a bit distressed: you think you've caught an opportunity, but you might just be helping others collect transaction fees and miners' earnings... To put it plainly, if you're a bit slow, you'll get squeezed; if you're a bit fast, you might just be helping bots explore the market. Especially during airdrop season, with anti-witch hunt measures and point-based systems on task platforms, everyone is competing like clocking in at work. As trading frequency increases, slippage and fees become more like hidden taxes. Thinking about it, I’m not speculative nor proud, I just occasionally buy some experience tickets. I’d rather move less, at least not turn "participation" into someone else's KPI. Anyway, the on-chain scene is lively, but the wallet still hurts for real.
