I'm not very good at... explaining those fancy roadmaps, but for ordinary people using Layer2, it's basically two things: save on gas, and don't sacrifice the user experience.

I now mainly use Layer2 for small, frequent transactions, and only go to the mainnet for three things: large transfers, important authorizations/revocations, and operations that need to be "finalized."
Anyway, mainnet is expensive, but at least I feel more secure.

Layer2 isn't about rushing blindly; I first check the bridges and contract permissions, especially those with one-click unlimited authorizations—less is better when possible.
Funds flow is unclear, governance is a mess, even cheap gas isn't appealing.
Recently, there's been a debate in the group about privacy coins/mixing compliance, and I think it's better not to treat your wallet like a wishing well: saving a few bucks with shortcuts can lead to more trouble when explaining later...
That's it for now, use it slowly, don't rush.
