A few days ago, a fan complained: Even though I correctly predicted the market direction, after four days of holding, I lost $1,000 in funding fees, and in the end, my position was suddenly liquidated. As soon as I was liquidated, the market immediately rebounded, and I lost my composure. $BTC $ETH

Actually, what killed him wasn't the rise and fall of the K-line, but those hidden pitfalls embedded in the trading rules — which is also the key reason many people get caught off guard.
The first pit is the funding fee. It’s charged every 8 hours; it seems small each time, but holding a position for several days can accumulate costs that directly eat up your profits. Always check the fee rate before opening a position; if it’s too high, be patient and wait. Avoid holding positions overnight if possible; try to open positions in directions that are favorable for funding fees.
The second pit is the liquidation price trap. Don’t think that 10x leverage requires a 10% drop to be liquidated. The platform adds costs like fees and slippage, so the actual liquidation price is 3%-5% lower than your calculations. Slight market fluctuations can easily trigger liquidation. Never go full margin; prioritize using isolated margin mode, keep leverage between 3-5 times, and leave enough buffer space in your account.
Don’t blindly trust high leverage: at 100x leverage, a 1% market move can instantly wipe out your funds. Plus, fees and funding costs are calculated based on leverage, making hidden costs extremely high. High leverage is only suitable for short-term quick trades; for long-term positions, choosing lower leverage is more stable.
Remember one thing: what exchanges fear most isn’t you making money, but that you understand the rules thoroughly. Many people lose money without understanding why, essentially because they haven’t figured out these hidden traps.
