mining nowadays are less profitable than the effort we spend. imho..
but if do it mostly for securing the network, it's till be okay..
What are you talking about?
Mining is still hell of a profitable. Otherwise there wouldn't be so much new people, farms and gear popping up each year more and more.
You just have to be up to date or figure out how to get cheaper, green (clean) or free electricity.
Mining Litecoin might not be profitable that much. But mining Bitcoin is. As is mining some other Alt coins.
Home mining might not be the thing anymore, but hobby mining and professional mining still is and it will always be.
