Recently, my wallets are increasing more and more, and the chains are also becoming more scattered. Stablecoins are scattered here and there, really broken into snack-sized pieces... My current clumsy method is: only keep "long-term inactive + minimal authorization" in the main wallet, and use small wallets on other chains as change wallets;

Set a fixed day each week for reconciliation, copy the balances of each chain into the same spreadsheet, and conveniently clear out unused authorizations, otherwise it just makes me anxious to look at.
Also, try not to split positions too finely, or eventually I forget why I put them there.
Additionally, the community has recently been arguing whether privacy coins and mixing coins count as crossing compliance lines, and I find it overwhelming... Anyway, I prefer to stay away from gray areas as much as possible to avoid issues like withdrawal getting stuck, losing out on gains, and adding frustration.
That's it for now, will change gradually.
