Many people ask, why do we still incur losses after messing around in the crypto space? The core issue is often not the technology itself, but the lack of systematic fund management and market information capturing ability.

Starting from a real case. A trader began with 3,000 USD and, through phased operations, accumulated to 287,000 USD within half a year. What is the logic behind this?

**Phase One: Risk Isolation (1-7 days)**

The most common mistake with small accounts is going all-in on a single asset. The correct approach is diversification: allocate 2,000 USD to spot trading, focusing on the top 20 mainstream coins by market cap (while avoiding certain specific ranks due to liquidity differences); dedicate 800 USD to arbitrage operations; and keep 200 USD as emergency reserves. This way, even if one part encounters issues, the account won't be wiped out in a single blow.

**Phase Two: Price Difference Harvesting (8-30 days)**

This is the core phase. Price discrepancies of BTC/USDT between different exchanges often exist. When the spread exceeds 1.5% on some secondary exchanges, and the perpetual contract funding rate remains below -0.02% for 12 consecutive hours, an arbitrage opportunity arises. The operation involves: buying spot on Exchange A to establish a long position, while opening an equal-sized short position on Exchange B. By leveraging the price difference, funding rate, and market volatility, profits are locked in. This strategy can achieve a monthly return of 3%-5%, with relatively stable gains.

**Phase Three: Trend Hunting (31-90 days)**

Once the account has grown to over 20,000 USD, you can start paying attention to opportunities in newer coins. These assets are often undervalued due to lack of recognition, but once their fundamentals improve or market sentiment shifts, they have significant upside potential.

Growing from 3,000 USD to 300,000 USD is not luck, but precise execution combined with an understanding of market microstructure. The key is not to pursue the fantasy of getting rich overnight, but to control risks and lock in profits at each stage.
