If someone has not understood this or, even worse, believes that it is not true, they should refrain from playing on this market until they understand it.

When there is a drop, is it the same value when it rises?

No, when a value drops by 50% and then rises by 50%, it does not return to its original value. This happens because the percentage increase is applied to a smaller value after the drop. Let's explain with an example:

### Practical Example:
Suppose you have an investment of R$$ 100.00.

1. 50% drop:
- If the value drops by 50%, you lose half the value.
- Calculation: ( 100 - (50% times 100) = 100 - 50 = 50 ).
- New value: R$$ 50.00.

2. 50% increase:
- Now, if the value increases by 50%, the increase is calculated on the new value (R$$ 50.00).
- Calculation: ( 50 + (50% times 50) = 50 + 25 = 75 ).
- Final value: R$ 75.00.

### Why does this happen?
- 50% drop: Reduces the value by half.
- 50% increase: Increases the current value (which has already been reduced) by 50%, which does not compensate for the initial drop.
Mathematically, a drop of ( x %) followed by an increase of ( x %) does not return to the original value. To return to the original value after a 50% drop, an increase of 100% (double) over the reduced value would be necessary.

### Conclusion:
- 50% drop + 50% increase: Does not recover the original value.
- To recover the value after a 50% drop, an increase of 100% is necessary.
Therefore, in cryptocurrencies (or any investment), it is important to understand that percentage drops and increases are not symmetrical in terms of their impact on the total value.
