Lately, switching back and forth between L2 and the mainnet feels like trying to find a balance between "saving gas" and "not exhausting yourself." The mainnet is expensive, but ultimately reliable and compatible, which is reassuring; L2 is cheap and smooth, but when it hits cross-chain/withdrawal windows, RPC issues, or blockchain explorer lag, people start to get annoyed... Anyway, my current approach is: for daily small transactions, try to avoid L2; if I need to hold long-term or worry about contract/bridge issues, I go back to the mainnet and pay a fee for peace of mind.

Recently, retail investors complain that validators earn too much, and MEV front-running makes ordering unfair. I also resonate a bit—sometimes you just want to settle quickly, but end up feeling suspicious about everything. I used to follow a certain account that kept shouting "X L2 beats the mainnet in experience," and I tried a few times. After getting stuck on nonce and rescuing with replay scripts twice, my mindset shifted from "learning and observing" to "forget it, unfollow." It’s not that they’re wrong; I’m just too lazy to gamble my time anymore. Now, my only rule is: if I don’t need to rush, don’t rush; if I can estimate gas, just estimate; don’t fight the sorting mechanism.
