if I will invest 10.000 usd (just an hypothesis) and if one or two years later I will have 15.000/20.000 back I should be satisfied. but if I invest 500 or 1000 I expect an exponential growth.
I don't know if this is the right project for an exponetial growth, honestly.
according to me, the greatest value of this project is the collection of data, and the management of the same.
this data is of high value, since the data of our personal tastes and those more intimate get great value
