if you’re a complete noob as we all were at some point, you might be wondering why all these tabs have two currencies listed. These are what we call currency pairs and what they represent is the value of one currency in relation to another currency. It’s really not that complicated. So, say as an American anytime you travel to Canada and you exchange your money there’s some value there that you’re getting some exchange rate there so when you exchange your US dollars you’re not getting that same number of canadian dollars back because you’re getting back the value in relation to canadian dollars so that’s the value of the u.s. dollar relative to the canadian dollar and that would be represented here as USD and CAN and as a currency pair so typically when you’re on a website or something you see the value of Bitcoin it’s implied that that’s relative to the US dollar so on a site like codacoin.com you’ll see the value of Bitcoin listed here and that’s in relation to the US dollar the nice thing about this site is you can easily change it to other currency pairs here’s the euro things like that another great place to see it is on the homepage of the Bitcoin exchange here see the currency pair Bitcoin/US Dollar that’s the same as what we saw here on the opening of this page – value in relation to value can also see other one of the other major ones: Bitcoin to the euro also how the cryptocurrencies are related to one another so Ethereum to Bitcoin here, for example So what these are called it the first currently listed is called the base currency the second currency listed is called the counter currency so when if you were to see something like BTC USD 1139 that means that the currency pair: bitcoin is the base currency US Dollars is the counter currency and it means that one bitcoin can be exchanged for 1139 US dollars so it’s the value of Bitcoin relative to the US dollar let’s go through some quick examples: so this chart shows the value of Bitcoin relative the US dollar the chart shows the value of Bitcoin relative to the euro this shows Ethereum relative to the US dollar the show’s etherium relative to Bitcoin. If you have any questions go ahead and leave them in the comments and I’ll do my best to answer. Have a great day.
