Did you mean could or should exchange? - US dollar is devaluing faster. - Bitcoin has been volitile to the up side and often steady. If the price starts to fall they could just start swaping to USD daily, if they wanted. Stupid to do that DURING a bull market though. - Giving an fiat exchange rate for the purchase seems like a good way to go at first, so people have context. - If they don't have a daily time horizon and they hold BTC, they'll be in good shape. - If they need to pay the fiat bills, then they need to pay the fiat bills. Doesn't degrade the fact that a business is taking bitcoin.
