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.
as far as i understood you pay the sites you like to support them. because instead of money from the ads they get it from you directly.
but like i said and i think you agree people are lazy and besides some geeks nobody will use it.
