Yes it is good if you don't have a job before joining crypto world but I will like to seek ideas from those that have reasonable jobs and I really want to know if you truly believe in Crypto so as to give away your job and fully dedicate full time to crypto or its not worth leaving everything because I see it as a long journey which I need to learn everyday.
From my perspective, cryptocurrency is also a form of job, depending on how serious you are about it. If people could go to the higher institution of learning to study courses related to blockchain technology as well as cryptocurrency, then i do not see any reason why it cannot be seen a s a job.
If you do not have any other job, just be serious about it and you can make it big from it. Then from there, you can begin to create multiple streams of income.
