Bitcoin uat me is a source of income, because I now no longer work all I focus on bitcoin.
For me, this is also a very good source of income. I do not imagine what I would do now without bitcoin.
To me I also consider bitcoin as a very good source of income too because when I haven't known bitcoin yet, I was having hard times to get some money. But because of bitcoin right now, my financial burden was being ease and that's why it is a very good source of income, even I'm just working for it as part time.
