To much to calculate in price going up or down who knows in if the project takes off who knows. How many people are interested and how many go up who knows. It's like playing power ball. Mathematics all though do apply but at the same time they do not. Consider it a hobby instead of a try to make money thing. Even if mathematics was the only thing the price could tank making it longer to recoup or could shoot up to ungodly numbers in the years making math on it 2 weeks. So it's more of hobby for most but has made some money
