Recently, I've been looking at that MEV bunch of "front-running," basically who can insert into the block first, and who gets the bigger advantage. The biggest impact isn't actually the whales, but those who are too lazy to watch the market and just make small trades once in a while: larger slippage, strange transaction prices, and they think they're just slow... Actually, they've been educated by the queuing rules.

A couple of days ago, before and after the upgrade/maintenance of that mainstream public chain, everyone in the group was guessing whether the project would migrate. I think whether it migrates or not isn't the point; moving somewhere else just means someone can front-run in a different way. Anyway, I’ve lowered my target: not chasing the best transaction, just avoiding confirming at weird times, using limit orders when possible, splitting trades when possible, and tightening wallet permissions. Making money is very mysterious; not losing coins and not being "front-run" too aggressively are what allow for long-term persistence.
