It is not only the Brave browser struggling to attract users with its advanced privacy features and crypto token rewards, there is also the CryptoTab Browser that tries to attract users with its crypto mining features. Both are Chromium-based browsers, so anyone familiar with Chrome will feel at home with either of those, although the Brave browser has a number of specific extra features and some differences. The CryptoTab Browser on the other hand is more like repackaged Chrome with a built-in CPU mining feature as an extension, while the rest is pretty much Chrome-like experience including compatibility with regular Chrome extensions.
The CryptoTab mining feature in the CryptoTab Browser uses your computer’s processor for mining and you get paid in Bitcoin. It is not clear what cryptocurrency you are currently mining, but supposedly the most profitable one is being switched constantly in order to maximize your profit. You have control over how many resources you want to dedicate to mining and how much will you get back in BTC mining also depends on what kind of processor you have available in your computer. Since it is CPU mining most likely some CryptoNight coins are being mined and since a single processor cannot mine that much, the CryptoTab Browser also helps you earn more BTC by inviting friends to try and use it. Again don’t expect to make a lot of Bitcoins mining this way via the browser, but it could be a nice extra running at a low priority and not bothering you while you do your job. The minimum amount you can withdraw is just 0.00001 BTC or 1000 satoshi.
