I saw someone making large transfers on a chain-tracking app, calling it a "smart money" signal, which reminded me of my own experience last year of constantly switching between L2 and the mainnet.

To be honest, when gas is low, I always want to go to the mainnet, thinking "it's the orthodox" — but then the transaction fails, and the gas fee already costs half a cup of coffee. Later I learned my lesson: toss daily interactions to L2, and only switch back when I need to do something big. After all, moving assets back and forth isn't that painful anymore.

But the experience is subtle: some protocols are only available on the mainnet, while some L2 versions have feature cuts. You have to try them yourself — there's no standard answer. Now I just... check the current gas first, then decide whether I'm feeling lazy today.

In plain language, the average person's compromise is "it depends on mood + wallet". Don't be coerced by the "must be on mainnet" narrative, and don't think L2 is the ultimate answer either.
