I only take one note: the mainnet is like a safe, and L2 is like a wallet — for small amounts, don’t bother fighting with gas.

When it comes to authorization, large transactions, or operations that might go wrong, I’d rather spend a bit more to go back to the mainnet — the experience is a bit worse, but I sleep soundly.
Recently, a bunch of new chains and Layer 2 solutions are doing incentives to attract TVL, and veteran users curse “mining, selling, and dumping.” I understand that too, so I only test with an amount I can afford.
Even if I save on fees, don’t get cocky; stop-loss is still necessary, and I’ll keep doing it.
