Integrating the two is the best thing, we can not live by relying on the uncertainty of the digital currency (crypto). too risky for real life. At least we are not 100% in a financially insecure zone.
50 real and 50 we pursue crypto. there are many ways to make money with crypto, it is tailored to the expertise we already have.
I like your idea. Why do we need to choose if we can do both? It is better to have two or more sources of income. You need not to let of the old one when you will have a new one.It is just how you handle yourself. As the saying goes, "the more, the merrier". But if it caused you too much stress and is not good for your health, then stable job is preferable.
