we already entered in the era of IoT, as we use to automate our home appliances with internet fridge, TV , AC etc....I see IoT have long journey ahead where user get rewarded for sharing their data.
As of now there are the companies like google , who don't reward the user for sharing their data...For example Google Map, Google show real time of traffic on Google Map and make huge money with Google map with the help of advertising.
Google show traffic data by collect data of Google user on that particular location. I think in future user will be get rewarded for its contribution.
That's a good idea.
Perhaps a decentralized version of it can be launched with the aid of IoT technology and users can get rewarded through that.
