It is very profitable if you are in island and use the volcanic heat to produce energy while using the cold at the surface to cool your hardware but no for the average person at home its not!
you don't have the kind of electricity deal required.
however you can join a mining pool like I did !
for my hardware I was break even in 11 months now I'm mining pure profit
and I don't have the sound of a vacuum cleaner in my apartment all day!
wow! it's great then :)
Whats even more profitable is altcoin mining and selling it for bitcoin ;)
