lo que quieres decir es que en el precio de 1 a 10 dolares , el porcentaje subiendo es una cosa y el porcentaje de 10 a 1 es otro diferente.

The difference between short and long
Let's assume a coin costs 1$ and its price rose to $10
If you enter a short position with 20$ at 50x leverage from the highest price, you will make a profit of $900
And if you enter a long position with 20$ at 50x leverage from the lowest price
You will make a profit of $10,000
Short is used to increase profits and not to generate profits
Long is always the basis of profit
