It depends on financial statuses and the ease of transacting in Bitcoin is ones home country. If I spent my income regularly and there is very little I can get in actual BTC currency, I would prefer to be paid in fiat or a portion in fiat and the other in BTC, rather than having to convert to fiat whenever the need arises.
It depends on the company that you're working for if they allow what you've said half portion of fiat currency and bitcoin. But what's the problem of converting to fiat? You can pay bills and expenses with the use of bitcoin for a less hassle transactions. During times like this, you are not allowed to go out so what do you think is the solution for that? That's why there are companies and businesses who accepts bitcoin as a payment, and bitcoin is a digital currency, besides of it being a store of value, it can also be used as a mode of payments.
My decision would also lightly depend on the organizations' relation of salaries to fiat, i.e, if salaries are permanently and averagely fixed in BTC values and would not be adjusted during a pump or a dump, I may consider getting my payment in Bitcoin.
Yeah, you should check first if the organization have the kind of attentiveness to that kind of idea. Some organizations are very strict and they just follow their rules and regulations without having any consideration to their workers. If I were you, I will choose bitcoin over fiat if you really want to have a bigger value. Also for you not to spend your money in some unuseful things and not be wasted. If you received bitcoin, it will just remain at your wallet and you can't spend it quickly because it will undergo so many process before you convert it into fiat currency.
