Recently, multi-chain wallets are becoming more and more like drawers filled with various cables, always missing one when you look for it.

My approach is pretty simple: divide into three categories based on "use case"—one for daily small amounts, one for long-term holdings, and one for playing with new chains/airdrops; then add a very simple table that clearly states which chain, which address, and what it's for.
Just spend ten minutes on the weekend reviewing it.

Seeing large transfers on the chain or hot and cold wallets moving on exchanges, the group starts shouting "Smart money is coming," I usually just treat it as passing news, making a note but not chasing after detailed analysis.
Honestly, what multi-chain fears most isn't losing a little, but when the ledger gets messy and you don't even know where your money is.
My biggest fear isn't slowness, but chaos—slow can be waited out, but chaos really means losing things.
That's all for now, going to have breakfast.
