Quite a good question. It will take some times for the market to find a "true price".
I think we all want to know how the $2000+ prediction is made up? Are there studies or something to proof this?
There is no such price for the average person. Total tokens are planned to be sold at 153,000eth. Even if we assume that 1eth is not $340, but let 1eth = $300, then $2000 = 6.66eth, then all the collected eth will suffice just to buy data from 22,973 people. Already in fact wrote above, that basically the data cost less than $1.
But for investors in DATUM this business will bring much more, since huge databases cost a lot of money.
The person who bought the DATUM tokens and the person who sold their data will receive amounts that differ thousands of times.
