Suddenly at 2 a.m., a message came through. A trader from the Pearl River Delta was trembling and almost crying: "Full position leverage SOL long, just a 4.2% pullback and I got liquidated... $6200 U.S. dollars went down the drain."

Looking at his trading record, the problem was obvious—he not only entered with full position but also didn't set any basic stop-loss. When the mark price hit the liquidation line, his account was wiped out instantly, with no buffer.

Recently, the total market cap of the crypto market adjusted to $3.8 trillion, with BTC's monthly volatility exceeding 25%. In this market, every day someone dreams of getting rich quickly with full leverage, but what’s the result? Most end up in the same pit—poor position management. Many confuse concepts, thinking risk is about leverage multiples, but the real killer is position size.

Let the data speak. A $1000 account with $900 fully leveraged at 3x, a mere 9.1% opposite movement can cause liquidation. Conversely, a $1000 account using only $90 at 3x leverage needs a 92.3% move to lose everything. Both schemes have the same leverage multiple, but their risk resistance differs by more than ten times.

Having seen too many liquidation stories over the past two years, I’ve summarized three "rules to survive," and using this method, my account has gained over 80% against the trend:

**Rule 1**: Never enter a position with more than 8% of total funds. For example, with a $6000 account, only open up to $480 per trade. Even if you make a wrong judgment, the damage remains manageable.

**Rule 2**: Limit single-loss to within 1.2%. Combine this with a 1.5% stop-loss to precisely cut losses and prevent small losses from turning into big ones.

**Rule 3**: When the market is unclear, stay flat. Wait until the weekly chart breaks key levels and volume ratio increases to 1.5-2 times before acting.

A follower once kept blowing up his account every month. After applying this logic, he went from $4,000 to $52,000 in five months. It’s not that he suddenly gained supernatural insight, but because he finally stopped reckless operations.

Another practical tip: spend an hour every Sunday planning next week’s targets and position schemes. It’s ten times more stable than staring at the screen all day and making random moves. Long-term profitability in crypto has never relied on luck but on discipline and position awareness.
