The premise of "making money from money" is that you first need to have a sum of startup capital.

The so-called snowball effect must ensure that it originally is a snowball, and that it rolls bigger on a long enough snowy path. It cannot just be a snow particle, and you naively wish to roll the snow particle into a snowball. Usually, the situation is that the snow particle cannot roll for long before losing its potential energy and stops, turning into a puddle of water, because you cannot guarantee that there are no small stones or pits blocking your way on this path.
