These days, I've been browsing on the blockchain and seeing a bunch of "arbitrage opportunities" that make me itchy, but honestly, most of the time when you click in, you're already paying someone else's transaction fees: you think you're capturing the spread, but in reality, the order book and MEV bots have already blocked the way, ending up as just the meat in a sandwich... When I get excited at night and want to add positions to chase, I look back at the transaction records and see it's all slippage + fees + emotional taxes.

Mainstream public chains are not upgrading/maintaining right now, and the group is guessing whether projects will migrate. I'm actually more hesitant now—when the chain gets congested or the packing rhythm changes, arbitrage and front-running bots love to exploit the gaps even more. My current approach is very simple: small test trades, preferring to miss out rather than chase those "seemingly lucrative" instant price differences, and first pull my hands back. Anyway, I don't aim for perfection, just for fewer losses.
