Using multi-chain wallets for a long time really boils down to one word: chaos.

My approach is pretty simple but effective: first categorize addresses by "risk level"—hot wallets only hold small amounts for interaction; frequently used wallets are for transfering/accumulating coins; cold addresses only receive and do not move funds.
Before each cross-chain, chain swap, or protocol interaction, think clearly about which "home" this money will finally return to, otherwise the fragments will keep multiplying, and in the end, you won’t even know whose gas you’re paying.

Also, don’t be too superstitious about on-chain data tools and their tags, honestly, many are outdated or even misleading.
When I see "some smart money," I now only treat it as a reference; the key is still keeping your own records: address notes, purpose, authorization time—write what you can.
Recently, I got overwhelmed by a bunch of tiny dust transactions, and after digging around, I found it was a contract I casually connected to months ago that I never revoked permissions for…
Anyway, I’d rather go through the trouble with new chains and wallets in the future than keep digging my own pits.
