I only take one note: don't be greedy with multi-chain wallets by putting everything into one "all-in-one" wallet. Separate them by purpose (main wallet stays cold, interaction wallet is for running tasks, test/spam wallets are for trying out). Keep only enough small change for the next gas fee on each chain, and regularly consolidate other funds into the main wallet. Anyway, when the fee rate becomes extreme, everyone argues about reversal or bubbles. As someone who just farms small profits, the key is not to lose assets or mess up the records—that's already a win.
