자동매매 시스템 써도 될까요? 🤖

Short answer: there’s no such thing as “plug in money and forget it.”
Most automated systems you see advertised fall into one of three buckets:
1) Curve-fit backtests – They look great on historical data, then fall apart when market conditions change.
2) Risk-masked strategies – Small wins most of the time, occasional large losses that wipe out months of gains.
3) Black boxes – You don’t know when or why trades are taken, so you can’t control risk when things go sideways.
Automation itself isn’t illegal or impossible — funds and firms use it all the time — but the difference is oversight. Real systems still need monitoring, drawdown controls, and rules for when not to trade.
If someone is selling it as “hands-off guaranteed income,” that’s the catch.
Automation can help with execution and discipline, but it doesn’t replace understanding risk.

They are almost all scams.

They're scams. That's the catch.
