If the salary is paid through Bitcoin but calculated in USD, then I think this isn't an issue. It would be the same as our signature payments: calculate payment in USD, but payment made in Bitcoin. I think this would be an advantage of saving Bitcoin as well if the receiver wants. All the funds we get from salary don't always need to be spent. So after spending the necessary funds for family, the rest of the funds could be saved for the future. So when Bitcoin pumps hard, they would have a handsome amount in their hand. It's like accumulating Bitcoin in a DCA strategy.
You are correct sir. I do not think it will be an issue if a person wants to receive part of their money in dollars and the rest in Bitcoin. Like I said earlier such an opportunity would enable the workers have a Bitcoin plans for their future and also they would be in profit if the price of Bitcoin keeps increasing yearly without them touching their Bitcoin. If It were possible to get such offers, I would prefer to save in a higher percentage of Bitcoin that the Fiat payment so that I will make a good lot of fortune from my Bitcoin portfolio when the price starts to appreciate.
