I was wondering if there was a plugin that make website viewers mine with their CPU for the website owners. Such a thing exists ? This could be interesting to add this to some websites and bring their creator a source of income and could permit them to don't display ads. This everyone is happy.
PS : Merry Christmas !
You would earn almost nothing.
A PC has a hash rate of say 0.05 GHz. The current network hash rate is 670,000,000 GHz. So 1 PC represents one thousand millionth of the network. And every month it gets worse. Over a year a PC mining continuously would be lucky to make a few cents. PC mining died in 2011.
Also people only stay on one web site for a few seconds. So even if thousands of people visited your super web site every second you will still make almost nothing.
