Is there a pie chart (similar to the hashrate chart) that shows the percentage of the market volume by exchange? I know this isn't hard to do and the result would be something like "90% MtGox 10% Others",  but I think it would be nice to see a more visual representation of this data. It would also be interesting to know the percentage of bitcoins traded in USD, EUR, GBP, etc.

MtGox does "own" everything, specially if you also consider MtGoxGBP, MtGoxEUR and the other currencies. Anyway, thanks for the chart :)

Why is btc-e not included in this chart, or am I blind?

That non-MtGox version is how the MtGox version should look like - the biggest exchange has less than 50%.

I think that better is to show only exchange "houses", not their tradable currencies. For example show USD/EUR/whatever on MtGox as one record.

Anyway thanks for graphs :-).

I was playing around with google charts and I thought about creating a web version of these. Surprisingly, bitcoincharts' API (http://bitcoincharts.com/about/markets-api/) only provides volume data from the current day. Does anyone know where can I get the monthly volume, or at least the 24h volume?

mtgox is too big.

After my newly acquired Javascript skills (i.e. copy/paste during the last couple of hours), I created a web version of these charts. The data is from the current day (UTC time) provided by Bitcoincharts. I will mail them to see if they can add the 31 days volume to the API.

The first chart has the bitcoin volume of each exchange. The second one merges mtgoxUSD, mtgoxEUR, etc. into one (the same goes for tradehill, intersango and ruxum). The third is a non-MtGox version (thanks to chodpaba for the idea). The fourth is the volume per currency.

awesome man

Thank you  8)

Valid viewpoint. But why? Why is the current situation with Mt. Gox' 80% market share less than optimal?

heh it's only a joke man related to mining, more than 51% into one pool ;)
 it's actually good for an exchange

It's not dangerous for the network (like the 51% hashrate problem for example), but monopolies are usually not a good thing. If there are a few companies competing in the same area, the consumer will get a better service, better prices, etc. I guess that the monopoly comes as a consequence of the free market, but I still find it strange that adepts of a decentralized currency trade 80% of their money through a single company.

Well, *technically* it's not dangerous for p2p network, of course. But crash of MtGox (for any stupid reason like they get busted for keeping marijuana in their office?) would be the real disaster for Bitcoin project and economy. Mostly because they hold milions of bitcoins and some huge amount of dollars. Many bitcoin businesses are holding funds there. Also trust in whole concept will be shaken a LOT ("where we should keep our funds when *even MtGox* is gone?"). I believe that only few believers will remain here after such disaster scenario.

For longterm success of Bitcoin project we need to spread this power across more exchanges, make that pie charts above more balanced. Exchanges like Intersango and Cryptoxchange, which are built as serious businesses (not like some anonymous guys from east Europe), looks trustworthy and are promising competitors. Let's see if they'll be successful - it's in the interest of all of us.

Yes, technically. We already have some exchanges built as a serious and professional businesses, such as CampBX or (the now closed) ExchB, but people haven't moved from MtGox. It is hard for new exchanges to get a decent market share, regardless of how professional they look.

Anyway, these companies are 4/5 months old at most so let's wait and see if that pie chart moves.
