Basic attention token is issuing by brave browser and it can be traded on all the major exchanges.

BAT tokens are issued according to your activity on browser and also you can earn the tokens exclusively by watching advertisements.

The speciality of the browser is it blocks all the ads on the web and doesn't allow any website to track your activity.

So it's very secure and designed to provide privacy for your data and bhevaiour.

You can download the browser through my referral and comment below to get a SBI share from me. 😃
