Here's what happens when you skip keeping a trading journal:

You repeat the same mistakes. Without documentation, you can't analyze what went wrong—emotional entries, bad entries, poor exits. You're essentially trading blind.

You lose track of patterns. Bitcoin volatility requires discipline. By journaling every trade, you spot recurring errors, identify your edge, and build a system that actually works.

Your account shrinks faster. Traders who log trades consistently outperform those who wing it. The data speaks for itself.

Start simple: entry price, exit price, reason for the trade, outcome. After a few hundred trades, you'll see what separates winners from the rest.
