I have been trading cross margin for a while now, and I want to share a few things with you if you're also considering using this method.

Cross margin can really help optimize your profits, but if you're not careful, you can easily lose all the funds in your margin wallet. Unlike isolated margin, when you trade with cross margin, your entire account balance is used as collateral, which is both an advantage and a risk.

The first thing I learned is not to margin your entire capital. I only allocate about 10-20% of my total assets on the exchange for cross margin, with the rest kept as a reserve. When entering a position, it's best to choose pairs with high trading volume like BTC, ETH, BNB, or ADA, XRP — these coins have high liquidity, making it easier to cut losses or take profits when needed. Avoid very small altcoins because they are prone to pump and dump schemes and are hard to exit.

Regarding leverage, I advise you not to be overly greedy. A maximum of 3x is enough; even 2x is safer. I've seen many people use high leverage and get liquidated painfully.

The most important thing is to always set stop-loss and take-profit levels before entering a trade. I usually use a 1:2 or 1:3 ratio between SL and TP, which is advantageous in the long run. Never let a trade run freely without an exit plan.

Another very important point is to monitor the margin level. When the margin level drops below 1.1, you'll be liquidated immediately, so I always try to keep it above 1.5. If you see the margin level approaching a dangerous threshold, consider closing part of the position or adding more margin.

I also pay attention to macro news such as FED, ETF, CPI because they have a strong impact on the crypto market. Before entering a trade, I always wait for clear signals from technical analysis on TradingView, avoiding FOMO.

One mistake I’ve encountered is trying to "hold through" losses when the market moves against you. That’s the fastest way to lose money. Instead, have a plan for both when you're right and when you're wrong, and execute it with discipline.

Currently, BTC is around 67.11K (+0.48%), ETH at 2.05K (-0.08%), BNB at 589.70 (+0.87%). These coins are still the best options if you want to start learning about cross margin. But remember, patience and risk management are the keys to surviving long-term in this market.
