Since I do not have any job, so I am already full time on bitcoin & it is not a bad option as I am earning enough for my pocket money .

Grats! I assume you don't have a family to care about and you don't have to pay bills right? I think you are a student and that's good that you have the opporunity to earn some extra pocket money.
I was in college even though I do not have a job but I also have another focus as complete a task from college and my time is divided between college course. so I can not like you. in full time work in bitcoin.
but despite that I use the break is a time to work in bitcoin. probably around 8 hours to work in bitcoin

is could call full time ?
I remember when I was in college I was struggling hard to start any online job so that I will be able to earn some good money along with my education, and I got success in it, at that time I divided my time in three parts, one part in college, the other one in study at home and the third one is spending time to earn some money online.
