I think that will happen gradually. You must believe that now bitcoin is accepted in several companies and this is certainly good for the future of bitcoin. Bitcoin will gradually become better known and more potential as a payment in the future. This is certainly good for the survival of bitcoin. I believe that future bitcoin will be great.
For developed countries that allow bitcoin to be used for payments, it certainly doesn't matter as long as the company is willing to use it and the exchange rate is agreed. However, not all are willing to be paid using bitcoin, so there must still be a meeting point where there is an offer to be paid using bitcoin or fiat money? Maybe it's fair.
