For example, starting from .5, you will lose .1, lose .15, lose .3, lose .6, lose 1.2, lose 2.4, lose 4.8, lose 9.6, and lose 19.2. As long as the principal is sufficient, you will definitely make a profit in the end, and this one will earn everything back. All trading systems are basically the same in fund management.
