Yeah and if you are an only earning person in your family and if you have responsibility on your shoulder its better that you continue with full time job and keep bitcoin as an additional income.
I would never resign in my day job if I am the only person earning in the family. Resigning inmy job will only create a gap in my financial source. And it might cause a problem, the reason is that if I am erning around 1000 USD in 1 month in my day job and earning another 1000 USD in bitcoin, it will create a financial stability problem because one of it will be gone. And having a multiple source of income will guarantee you that you can earn even if the other source is having a problem.
