Miner lets you to have life & hobbies & dont ruin your eyes with concentration on when to jump in game
This form of mining costs more in resources than you get in satoshis, is it that difficult to understand? In other words, there is no point into doing it if there is nothing to gain -- that should make sense, right? People get excited about browser mining, but they ignore the costs involved (costs that initially aren't visible). At the end of the day, everything being mentioned here (even the apps I came up with as example) are nothing more than a waste of time. You're far better off just getting involved into lending, which is really a form of passive income that gets you at least some returns.
It depends on what hardware you have and how much your electricity costs but the calculations I've made it is profitable on an old i5 for me. This is just the extra electricity that the mining process takes so it dependant on the PC being turned on and in use already. Lending is also a good way to make passive income but of course, you don't to have capital to put at risk to browser mine.
