Interesting idea pay with BTC to remove ads.
But why people would pay for removing ads when they will basically achieve the same goal while using other browser with ADBlock addon?
This ways they won't have to pay anything. If Brave works like this then I see no incentivize to use it just because they are different.
if you read the previous comments and if you also pay a visit to the developer's site you can see that this is only optional to pay the sites for supporting them not for removal of ads. the removal is another story.
the adblock is actually present in this browser and it is supposed to be so much stronger than any other ad-ons currently available for Firefox and Chrome.
