GBP... The price of a Domino's pizza hasn't changed in the last 6 month's in my area. With this site the price could feasibly change several times in a single day.
I think you missed the point. It all depends on what you consider the true price. If you measure in gold, your price fluctuated too. When Bitcoin gets world domination, GBP will be the one flucuating in comparison to Bitcoin, for the same reasons Bitcoin is fluctuating now.
As someone who doesn't own quantities of gold and doesn't travel around the world much the true price of anything for me is GBP. I think a lot of people would think the true price of something is that of their local currency.
I don't know what America is like. In the UK the Domino's website is very good, very easy to use. Sure you can use BitCoin but I don't understand why someone would want to use BitCoin and pay a premium to do it.
>If somebody can match your key to your person they can see your entire purchase/sell history.
Which is why keys aren't attached to individuals and can be changed with every transaction.
Yes, some traceability is inherent to blockchain crypto-currencies. But using them anonymously is still easier than with any other electronic payment method.
The whole issue is that the pizza-seller takes GBP, or USD, or CAD, or whatever, not bitcoin. Thus, if the price of pizza fluctuates day-to-day in Bitcoin due to the fluctuating exchange rate, using Bitcoin by conversion to GBP or USD to buy pizza is pretty dumb.
Call me when a pizzeria starts actually taking Bitcoins.
Makes no sense to measure fluctuations without a reference. Are you saying the numerical value solely determines the price? If so, the pizzas were very very expensive in Italy before they got the Euro.
Well, that's a function of the 'true price' being measured in a different currency than the one you're paying in. Some retail businesses that accept foreign currency rectify this with a flat exchange rate.
For example, in Canada businesses (at least on Southern Ontario) will generally accept payment in USD instead of CAD, but they tend to have a flat exchange rate (e.g. 1 USD = 1 CAD or 1 USD = 1.10 CAD). If they priced the exchange rate to the current exchange rate as measured by some currency exchange, that would be different.
You run into this same issue when using a US credit card in Canada. The credit card company will exchange (and usually charge an extra ~1% charge). IIRC, they use up-to-date exchange rate info, so technically the price in USD is constantly changing.
