Companies make money on that data from the devices they own--for example VW's automonous taxi intiative or google delivery drones. Also, they can buy the consumer data from the consumer, which gives them better analytics and market research. Most companies have silos of data sitting in dbs that could be sold on the openmarket through the data marketplace (though that doesn't only apply to data collected by sensors).
I am smart enough to thnk with my head and not to fall into ''data marketplace''
Every blockchain can do that
And once again: I will seel data to Google, not Google to other people.
That's why IOTA is a treat for Amazon, Google
Every blockchain can do feeless and scalable, the things needed to make a data marketplace feasible? Maybe you should go tell them that, because IOTA's the only one testing it. Would be weird that in market of overpromising money grabs, that one of the biggest money makers would be ignored by something anyone can do. /s
If the tangle can't find as much as nodes possible the network will relay on coordinator forever.
What makes you think that a lot of people will join the IOTA network making it stronger?
