MEVが小規模トレーダーに与える影響

It's definitely a tax, no doubt about it. For small trades, the gas fees already eat into profits, and then MEV just adds another layer. It's frustrating to see your order getting sandwiched.

Has anyone actually tried using those 'MEV protection' services or decentralized sequencers? I'm curious if they make a noticeable difference for smaller accounts, or if they're just adding another layer of complexity.

I'd argue it pushes smaller traders towards less liquid pools or exchanges where MEV isn't as prevalent, or at least less aggressive. It's not ideal, but it's a way to avoid the worst of it.

I think 'tax' is a bit strong. While MEV certainly extracts value, it's more about understanding the mechanics. Using limit orders instead of market orders can help, and being strategic about when you trade can reduce exposure.
