Someone on social media introduced me to CryptoTab Browser, that I will be using the browser to mine and earn Bitcoin. With the little knowledge I gathered from this forum, I was able to tell him that bitcoin requires complexity of computing system with high energy consumption in order to be mined. Which a smart phone cannot do. He insisted that he and his friends have been mining and earning BTC in the app. He went further to show me his BTC balance he earned.
Please, can someone tell me what's actually going on in the browser, as I strongly believe it's not Bitcoin mining that is happening there.
