just be in balance in all. earning bitcoins can be so addicting because of its rate as of now and increasing price. theres always a way to balance it. like spending time with family on weekends and do your bitcoin works/earnings on weekdays with a limited amount of time.
You are right. Still, some people are getting their bitcoins from faucets as they are considering it as a free money so they do not want to leave it off. As faucet earning is very low, they might need you to work for some long duration. Those kind of people must have some proper plan for spending time for bitcoin earning.
I agree this kind of free earning thinking has chances to turn into addiction to affect your family life.
