I did both, at first I had difficulty dividing time between two jobs.
but now I am used to it, and can manage time well. the most important thing is not to sacrifice time with your family just to work.
Yes, I did both too. I have a real offline job that gives a lot of benefits while at the same time doing cryptocurrency during my vacant times. I just can't give up my real job because it is very helpful to me and to my family specially my insurance benefits and same with hospitalization. I can do both without sacrificing any one of them. It is not easy but I can handle well.
