Because like every single other token being created recently, its actual use is almost zero and it's just a means of generating shitloads of money for the creators.
I use the Brave browser, and even I can see that it's trash.
I did not knew that they have already released the browser,is it the mobile version you are talking about.The problem with BAT is that people jumped into the coin when it hit the market as no one got the opportunity to purchase during the ICO period and then people started dumping it ,as simple as that,we could see any movement if the business model clicks.
I'm pretty sure the Browser was out even before they did the ICO. However, it was the implimenting BAT into it that we were all waiting for from my understanding. As for the price, i'm just waiting on it to go down a bit more and i'm going to buy some up for when it does come back up. Which, i'm fairly certain it will.
