Very small wallets can produce misleading data. A small account may catch one strong move and show a high return percentage, but that does not necessarily mean the strategy is stable.
Total PnL is useful for a first glance, but you need to know whether the profit came from repeatable trading or only one or two outsized trades.If most PnL came from a single trade, save the wallet and review more history before considering copy trading.
Too few trades means the sample is weak. Too many trades may indicate high-frequency or very short-term execution. High-frequency strategies are more sensitive to slippage, execution latency, and fees when copied.
Drawdown matters more than headline return. A wallet can make a lot of money but still experience deep drawdowns. Your copy trading account may not be able to tolerate the same loss path.
Be cautious with wallets that suddenly spike in recent performance. A stronger candidate performs well recently without showing obvious loss of control over a longer period.
