I think it very much depends what kind of data you are willing to sell. The more specific and tailored to companies' needs the more you can earn.
For 100$ a year I wouldn't even bother selling my data, but I guess we are in a very early stage to speculate about that
Didnt they say your data is worth up to 2000$ per year? That would be a great amount but 100$ really sound too much work for such a low yearly income.
I'm sure that even $ 100 a year will not give. It's too expensive.
Data is worth way more then 100$ a year. You underestimate how much Fb/google make on creating adds that you want to click on (based on your data)
The prices depend on the quality of your date, or it should be, i don't think a celebrity would be paid the same as we are, so how to determine how valuable is your data, hope datum can help determine that, if not, then datum it's not so good, still a good idea though.
Celebrities will not sell their data. Why should they do this? For $200 or even $2000, they will report that they have hemorrhoids for example?
The application is intended for the average person, and then these data will be generalized and formed into large databases for sale to companies, but already at a different price, where will the profit come from.
