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.
You did the right thing, in order for you not to depend on cryptocurrency then you should have your corporate job and earn cryptocurrency while working to have stable income.
