Righto, I was mixing info from multiple threads. So that makes it easier because I potentially empathized with people who may have needed to fight for a refund for whatever reason. Who cares if the site states the USD price? If you go to place an order and they're using an exchange rate you don't like, don't buy it. If the ticker was stuck, using an exchange rate you don't like, or whatever else, you could have not bought it and moved on, or requested an updated total, etc. How is it any different from having a sales thread where you say you're selling a camera for $700 and then when someone decides to take you up on it, you look up the BTC price and give them a BTC address and total? There was a thread where OGNasty said they were selling a coin for $1750, so they converted that to BTC and posted it on the site. OGnasty may have used an autoupdating ticker, or maybe done it manually? Regardless, the solution to your problem was pretty minor.
you have missed the point.
in the big picture what it is priced in can and often will affect how you get refunded. Take bitmain for example, you pay them 2600 in btc for a miner based on the exchange at that moment because they price it in USD not btc - they convert it yes. If you get a refund, which is rare - but I did get once - and even though I paid in bitcoin, and was refunded in bitcoin, the amount I got back was based on USD value of bitcoin at that time.
so whether something is priced in btc or usd matters when there has to be conversions.
