Has anyone actually tried and earned something from browser mining?
I actually tried using the freebitco browser miner for around 15 minutes and I did not earn a single satoshi.
It would be nice to see estimates for example how many website visitors you need daily (and over what amount of minutes do they need to stay online) in order for you to earn a certain amount of satoshi. Right now it seems like there is too much hype over something that will not be profitable unless your website already has a lot of traffic which by then means it already is profitable anyway.
This website:
https://coinhive.com/Mining of Monero.
With mobile phone that gives 5 hashs you can earn 1$ in month, if you will mine 24 hours in day.
With good laptop with 25 hashs you can earn 5$ in month.
This is useless for solo mining. But if you can do some project or some game and few thousands of people will play into it you can earn normal money. Maybe even 5000$ in months. But you can earn also with different methods if you find thousands of people
Anyway I like idea of captcha with mining! If google will do from their recapthca mining captha, they can earn millions and millions!
