Have you ever thought about it, that exchanges can actually become your ATM? No need to guess the market correctly, no need to watch the charts every day, and you don't even have to believe in K-line mysticism. The key is to change your mindset—think of yourself as a casino boss, not a gambler.

I have tried this method for 5 years, with zero margin calls, turning 5000U into a seven-figure sum. Frankly, it relies on understanding probabilities, managing risks, and letting compound interest do the heavy lifting. Today, I want to share three core practical strategies.

**Lock in profits and give your gains a bulletproof vest**

At the moment of opening a position, place both take-profit and stop-loss orders simultaneously—don't wait. When profits reach 10% of your principal, immediately transfer 50% to a cold wallet, and use the remaining "earned money" to continue rolling over positions. The benefit of this approach is: if the market keeps rising, you enjoy compound growth; if it reverses, you only give back at most half, keeping your principal as steady as a mountain.

Over 5 years, I have used this method to realize profits 37 times, with the largest single withdrawal reaching 180,000U in one week. Later, the exchange's customer service even verified via video whether I was laundering money—because I was withdrawing so frequently.

**Three timeframes—turn others' margin call points into your entry signals**

Look at the daily, 4-hour, and 15-minute charts simultaneously: the daily shows the big trend, the 4-hour defines the trading range, and the 15-minute helps pinpoint precise entry points. Use two orders for the same coin—place a buy order on a breakout with a stop-loss at the previous low on the daily chart; set a limit order to short in the overbought zone on the 4-hour chart.

Both orders' stop-losses are controlled within 1.5% of the principal, but take-profit targets are set at over 5 times. The market spends 80% of its time in consolidation; while others get margin called here, you profit on both sides. Remember the Luna crash in 2022? It plunged 90% in 24 hours. My long and short take-profits triggered simultaneously, and my account gained 42% in a single day.

**Stop-loss is your ticket—small losses for big gains**

Many people fear stop-losses, but in reality, they are the cheapest ticket to survival. Use a small risk of 1.5% to exchange for the chance to control the market—if the trend is favorable, move your stop-loss to lock in profits; if not, exit immediately.

Long-term statistics show my win rate is only 38%, but the ratio of profit to loss is 4.8:1, with an expected value of +1.9%. In other words, for every 1 dollar risked, I can earn 1 dollar 9 cents. As long as I catch two real trends each year, my returns surpass bank savings.

**Three iron rules to prevent fatal mistakes**

Divide your capital into 10 parts, use at most 1 part per trade, and never hold more than 3 positions simultaneously. After losing 2 trades in a row, shut down and go to the gym—don't open a "revenge trade"—that's when human nature is most prone to problems. Also, double your account every time it doubles, and take out 20% to buy US bonds or gold, so you can sleep peacefully even in a bear market.

The method is simple, but executing it against human nature is deadly. Just remember one thing: the market isn't afraid of your wrong judgment; what truly scares you is that after a margin call, you may never recover.
