Whoever has an additional amount can enter with a small sale

High risk, but if it’s managed well, it can yield good profits

Whoever enters should do so with an isolated margin and it's preferable not to have a large leverage due to its large fluctuations

Whoever enters should take profit at the first 10%, raise the stop-loss to their entry, and then at a profit of 20% either close or leave part open and close part.
