No, because the office work and work in the office can be combined, as Bitcoin can be used anytime, then working in the office can use Bitcoin.
I totally agree with your opinion. I think we should choose both because our income will increase more.
Anyway, stable work is better than working with bitcoin. You need to get a stable job to take the capital to invest in any altcoin you like. Do not take risks and avoid risks.
Yes it can increase our income if we choose the two, but i think that more important is that we cannot depend on crytpo currencies for living, because still we are not sure that either we can get permanent income from crypto trading or not, therefore if we have our day job that is a big support for us from where we are getting a permanent income, therefore the most important is to continue both.
