Lately, I've been switching back and forth between the mainnet and L2. To put it simply, it's about finding a compromise between gas fees and user experience. For small transactions, I mostly avoid L2: transfers, participating in activities, trying out new protocols—just run a small position with a new wallet first, and if something goes wrong, I don't mind. If I need to hold a long-term position or deal with permissions/large withdrawals, I still go back to the mainnet. If it takes longer, so be it; I just want to feel secure.

As for cross-chain bridges... I've seen more reports of theft these days. I now try to avoid crossing if I can. If I must, I do it in batches and choose routes with deep liquidity. Also, when oracles suddenly report errors, the group now defaults to "waiting for confirmation." I also stay cautious: wait a few more blocks, check the on-chain status a couple more times, avoid impulsive actions, and sleep better at night.
