7 years of experience in the cryptocurrency circle, summed up 8 iron rules:

1. If the funds are less than 100,000, only buy one coin; 200,000-300,000, buy two; 500,000, buy 3-4. Even if the funds are more, do not hold more than 5. Concentrate funds in the bull market, and hold a small amount when the market is not good, so as to stop losses in time.

2. The only purpose of reading news and learning technology is to improve the winning rate. Trends determine everything: rebounds in a downtrend are mostly to lure more, and declines in an uptrend are mostly to dig pits. Don't fantasize about buying at the bottom, and don't guess the main trend.

3. Set a fixed stop loss when losing money, and don't move it down. When making a profit, keep raising the exit point to prevent profit taking.

4. Buy decisively and sell resolutely. Hesitation will inevitably miss opportunities.

5. Don't indulge in intraday short-term trading, small fluctuations will disturb the mind. Big money depends on following the trend.

6. Don't buy at the bottom because of a large drop, only 20% of people in the market make money.

7. Only trade when the market is active and stay flexible.

8. Before adding positions, ask yourself: If you haven’t bought now, will you buy again? If the answer is yes, you can add positions. It is recommended to fully invest before October and wait patiently for the bull market.
