Getgems is pretty interesting. Its basically a Telegram clone so Telegram users can move over to it. It has a Bitcoin wallet and Gemz cryptocurrency inside the app. You earn gems by inviting friends and using the app. The disrupting thing is the advertising platform they plan, ie Advertisers have to pay gems (tokens) to a user they want to reach so cutting out the middle man. No more rich ass-holes selling our data basically.
I decided to go and buy some of the token cause I have a bunch they could get awful valuable if this app gets user onboard.
