If you want to turn a small capital into a big business, here are some tips:

1. Picking Coins: Follow popular strong coins and avoid those obscure coins with no attention. Look for coins with a growth rate of less than 7%, so you are following the footsteps of the big players.
2. Trading Cycle: Short-term operations, like guerrilla warfare, quickly enter and exit, and avoid dragging things out.
3. Trend is King: Don't be afraid because the price is high, or buy because the price is low. Follow the trend and don't scare yourself.
4. Position Management: Start with a position control of 20% to 30%. If the market is good, gradually add more, but don't add too much at once. It should be like a pyramid, with a large base and a small top.
5. Moving Average Indicator: The 10-day moving average is the main operation line. When the price retraces to this line but doesn't break below, it's a good time to buy.
6. Review: Remember to save your trading records and analyze the reasons for each loss, such as entering too early, being too nervous, holding for too long, or having too large a position. This way, you can keep improving.
