Review on Instars by Věra Filipová

This is one of the platform I have joined from beginning as I like the use case of getting paid for your data, esp. in marketing.

From the simple questionnaire it evolved to the receipt data mining platform. You are paid for sharing your shopping experience in their native token or in US you can earn DAI. It is cool as it utilizes their very own main net. You can use app (only for Google).for your convenience. I have accumulated decent amount of tokens and reffered to lot of friends (they have also refferal program) which join me in accumulating. Their token is traded at exchanges so there is a liquidity and opportunity to exchange it. Their token can be staked to get even more. It is easy to use, rewarding and overall I can recommended to try.
