Fluctuation:
I think I know what that is like. As a freelance English Teacher in Vietnam, my monthly income fluctuated during my five years there. So, basically, you are like a starving artist in some ways. In some ways, actors may experience some of this. Perhaps, models have to deal with it too.
Especially Writers
Writers probably struggle a lot more than some of the other occupations, historically perhaps, which reminds me of the life of the fictional Anne of Green Gables who was trying to become a writer and yet she was a woman and they didn't like that and maybe they should have.
Get a Normal Job
I get that as well. Get a job, they say. So, some of us get it to various degrees. With the help of the Internet, we may feel less isolated. And a lot of people prefer a normal job. It can be tougher being your own boss or being some kind of private contractor or freelancer or whatever people may want to call it.
Your New Job
It sounds like good news. Flexible. It does not sound very stressful like what you might see inside hospitals where many nurses have been overworked it seems. So, keep up the good work. Crypto is a good backup system for money. The only thing better is gold, etc.
