Using a multi-chain wallet for a long time really feels like filling a drawer with small receipts: a little here, a little there, it doesn't seem like much, but when added up, it's quite frightening.

Right now, I basically focus on two things: separating "frequently used + long-term" wallets, clearly naming the addresses (otherwise I won't recognize them in a couple of weeks), and creating a simple fund flow diagram so I at least know which chain the money is looping through.
Recently, there's been talk about miner/validator income, MEV, and unfair ordering—basically, retail investors suffer the most because "you think you're exchanging the same amount, but each chain has different rules."
If I hadn't been lazy and spread my assets across four or five wallets, I might have avoided a lot of pointless cross-chain and authorization anxiety...
Anyway, now I prefer to keep things simple, so I can sleep peacefully without unnecessary fuss.
