Agreed, day time job is better at this stage in compare to bitcoin, as we can never expect stable income from bitcoin, but day job offers you financial security.
That's the reality that day time job is way better than having a bitcoin job since bitcoin doesn't give an assurance that you could get a well
compensated job rather than the company that you are working with you day job.
The thing is if the bitcoins downfall happened (just for an example), and you are a full time bitcoiner. And you are trying to apply again
for a daily job, I think your bitcoin portfolio or bitcoin experience won't be considerable by the employer since it is digital and there is no paper
reference that can certify it.
That's true and if you have descent gap in your professional job then no employer will entertain you and at that stage it would be difficult to find good job.
The fact is that you can focus on bitcoin in your extra time, you don't need to leave your job for bitcoin, what will you do in future if bitcoin simply disappears?
