Achieving financial freedom in the cryptocurrency world, here are seven fundamental rules!

1. If a strong coin drops for 9 consecutive days from a high position, make sure to follow up promptly.

2. If any coin rises for two consecutive days, make sure to reduce your position promptly.

3. If any coin increases by more than 7%, there may still be an opportunity for a rise the next day; you can continue to observe.

4. For strong bull coins, make sure to wait until the correction is over before entering the market.

5. If any coin has three consecutive days of low volatility, observe for another three days; if there is no change, consider switching coins.

6. If any coin fails to recoup its previous day's cost the next day, you should exit promptly.

7. In the rankings of increases, if there are three, there must be five; if there are five, there must be seven. For coins that have risen for two consecutive days, enter at a low point; the fifth day is usually a good selling point.
