How cross and isolated margin differ, where a liquidation stops, and which mode fits which style.
How to spot fake support and phishing sites, and how to set an authenticator and an anti-phishing code.
Win rate alone is a poor filter. Look at return history, max drawdown, holding time, and payoff ratio before you copy someone.
