Live bitcoin map
Via Business Insider, a live map of which currencies are being spent on Bitcoins
The Business Insider post says
[I]n the time we’ve watched it, it becomes clear that China really is big into Bitcoin relative to the rest of the world.
Below is a brief snapshot of what we saw in which the transactions were dominated by Chinese trading (at other times it’s more even, with more US action).
A big reason for the variation would be time of day, but my map above ran for about 17 hours, and it shows much more US than Chinese bitcoin activity &#; and even more Australian than Chinese. Longer sampling times are clearly needed to say anything definite.
The map website says &#;watch the world&#;s currencies flow into BTC in realtime&#;, which is the sort of exaggeration that&#;s unfortunately common with bitcoin enthusiasts. These are exchanges of bitcoin for other currencies: one person gets USD and gives up BTC, the other person gets BTC and gives up USD. The only net flow into (or out of) bitcoin comes from the seller&#;s profit (or loss) as bitcoin changes in price &#; and that can be much more easily and accurately estimated from the exchange rates, without needing to track individual transactions.
