No, i won't. Because in my country bitcoins is not popular so i can't spend my bitcoins. I prefer receieve my salary on fiat, so i can use my money directly. No need to exchange the bitcoins into fiat first.
Yes and to prevent a hassle one since salary will be used the moment you receive it. If people wants bitcoin then just buy it using some portions of the salary.
It's way more less hassle. Salaries are meant to cover all our daily needs. If there's an extra then they may consider to buy bitcoin.
