Most users of the cryptocurrency-powered Brave browser don’t actually take advantage of its crypto features, according to CEO Brendan Eich.

During a livestreamed conversation with Binance CEO Changpeng Zhao, former Mozilla CEO and JavaScript creator Brendan Eich revealed that at the end of April Brave already had 13.8 million monthly active users, but that only 1.7 million (12.3%) were using its Basic Attention Token (BAT) ad program.

Brave’s BAT ad program rewards users for seeing ads while browsing the web with the Ethereum-based token. The browser, by default, blocks ads and trackers to preserve users’ privacy, and instead uses its own ad network based on the token.

Users have to opt-in to see privacy-preserving ads on Brave, and are rewarded with BAT every time they see one. These are, by default, distributed to content creators on the web, although users can opt to hold onto the tokens or to tip them.

During the livestream, Eich explained that the current advertising system see advertisers spend “a lot of money” to get users to buy their goods, and as a result ads that track them are shown on the web. Users, however, only get “the ads and the tracking” and don’t see any of the money. Brave’s ad system hopes to help with the problem.

Eich added that Brave is working to make the BAT ad system more attractive to users. He said:

When we first released [Brave Browser] on desktop, it was 40% of the desktop browser share and as we added mobile we found people were less willing to use it, but we are working to make it more attractive to use by making it more convenient, making it reward the user more.

The livestreamed discussion between Eich and Binance’s CEO comes shortly after both firms partnered to add a Binance widget to the new tab page on the Brave browser. The feature was rolled out earlier this month.
