The more wallets you have, the more scattered the chains become. Do you really need to rely on your brain to remember everything?

I eventually accepted: don't pursue "everything in one place," start by layering assets so it doesn't get messy.
Use a main wallet for daily spending, and separate on-chain interactions with a "dirty wallet."
Keep long-term holdings cold and infrequently moved.
For cross-chain, try to stick to two or three commonly used routes, and treat others as if you didn't see them...
Fragmentation isn't the problem; the problem is that every time you want to "try it out casually."
Recently, with the expectation of rate cuts, the dollar index has been swinging along with risk assets, which also reminds me:
Don't amplify management complexity; keep it simple whenever possible.
