As a seller you'd simply denominate the prices in USD, keep some percentage of the btc as it is very likely to appreciate and convert the rest to USD as soon as possible to mitigate fluctuation risk.

As a buyer, you'd just purchase btc in the moment preceding the transaction or spend from your own hodlings if it seems like a good moment to reduce exposure.

Volatility is not that big of a deal.
