Okey, in my opinion, this is how much salary you can get each month for your full-time job? Can you have more time to participate in encryption at the end of your work?
My monthly salary is $1800. I can only use the time after work to participate in encryption, because I am not willing to give up my previous work, I love that job. So I can't suggest you do this. Of course, if you have more experience and insights on encryption, I believe that even if you invest full time in encryption, you can earn more.
