Smart money: how 'smart' wallets are tracked and why it only half works

The idea is embarrassingly simple: find wallets that consistently make money, and copy their trades. An entire industry has grown up around it - from dashboards to copy-trading bots. It works - halfway, and it's important to understand why.

How smart money is found

Analytics platforms rank wallets by realized PnL, win rate, and early entry into winning tokens. Then come the labels: "early buyer of X," "sniper with a 70% win rate." You can track them manually (address alerts) or with auto-copy bots.

Why it only works halfway

• Survivorship bias: a wallet's win rate is the past; the stats are full of "one-meme geniuses" who dump everything afterward.
• You copy the entry, not the exit: smart money sells fast and without a tweet - by the time you react, part of their position is already in profit off people like you.
• Aware they're being watched: top wallets know they're tracked - and use it: staging a visible buy on a well-known wallet, dumping from unmarked ones.
• Copycat crowding: a popular wallet means a crowd of bots on every one of its trades: copycats' entry price is systematically worse.

The working mode: smart money as an attention filter (what to watch), not as a trade signal (what to buy). When a smart money buy coincides with our on-chain verdict - now that's genuinely interesting: we track it in the section.
