We all know that bitcoins price changes quickly because of its demand So if some online shop sells products and pricing it in bitcoin,
How can we price it ? Should the price change also like btc?
The best way is to fix the price of the item or service in fiat values. This ensures that the payment will always for the full amount, regardless of the pricing of bitcoin fluctuating.
I agree on this, putting the value of the item in fiat will guarantee that you won't get bankrupt or overcharge due to Bitcoin price change, After setting up prices you can then get some BTC to USD convert reference and use some of plugin that convert the price to current bitcoin to usd exchange.
