If there was a source of steady income yes, but i dont see this as a good way right now.
I think you can get a steady income from bitcoin. such as working in signagture campaign? you can earn a steady income every week or every month? I think if you're willing to work hard no matter what will be a great way and profitable :d
I do not think the income from signature campaign is enough to replace your full time job. Though income from.signature camapign is bigger than faucet, it is still not enough to provide for a person with a family to feed. So, if it is the only source of income from bitcoin, it is better to preserve your full time job and reserve bitcoin for part time activities.
You can't just say "NO" to an advice because all of it depends on the location, status in life, and cost of living of the person. If the person gets much money out of doing signature campaign (e.g. he's enrolled in a high rate campaign and he has a high ranked account, he has some alt accounts) then he should focus on it.
We all know that signature campaigns aren't created to feed a family of a user. But let's be more practical, if you're getting insufficient amount of money in your day job, then why don't focus in signature campaign where you can earn much more? In third world countries, getting enrolled in a single campaign in here is like having a day job already if you are not a degree holder.
