Why in the marketplace some products are sold for Phore (PHR), and some for pounds sterling?
Payment occurs all the same in Phore (PHR)?
All products in the marketplace are sold for PHR coins.
Other currencies are listed for convenience, but when paid, everything is converted to PHR
What resource is the cryptocurrency rate calculated on?
This is not very convenient, because I can pay at a very unprofitable rate. You may need to add stablecoins for payment.
