My problem was this .......... If I pay £1 for a loaf of bread in the UK and $1.28 for bread in the USA then if we go to cryptocurrancies would I pay 2 yingyang ( ok I made the name of that crypto up for illustration purposes ) in either country ?
Would there be one unified money with no exchange rate between countries ?
After many conversations I think I now have the basics - each cryptocurrency is different, that each one has its own value and the market determines how much each is worth in each country. The likelihood is there will be thousands of currencies each worth differing amounts and each having its own buying power but there will be no universal currency that is the same world wide.

Now I am not saying I am right - I have just worked 27 hours in 2 days and am tired - so if I am wrong please tell me ( and give poor
