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.
I think. that you do not need to give up the main job, because you have a long way to go before you get enough profit in the crypto world, and if you do not have money to live, then you can leave the crypto without waiting for the results
