Wibson is a great data market place, still need have to improve as most dAPPs but the following facts shows how big this is:
+ Created an app before launching WIB, Alpha app was available on Google Play Store and TestFlight. in Alpha App users got Wibson Point, which you can change it for VISA virtual card, Spotify subscriptions, Uber rides and more! I got a 30 USD VISA card byselling my data. By testing it and with users feedback, they were able to improve it and launch the official APP.
+ Wibson protocol. Its really amazing how it works and the figure on Notaries to validate data (today we live in a world with too many bots, fake data and of course fake news....)
+ Not ICO was made. I believe this is HUGE. Projects that choose this path are showing that in the long term it generate trust.
+ Official dApp was launch and in less than 3 months it got more than 100k transactions. Is the second dAPP on amount of transactions. Also, it already has more than 8k holders.
+ I used it since alpha App, I connected my data sources, sold my data and got WIBs very fast. WIB is already on a couple of exchanges and seems that are more to come, showing that crypto community supports it.
+ Great community and customer support on Telegram
+ Telefonica invested on Wibson:
