The Distribution of Bitcoin users

I wanted to get an idea of the distribution of bitcoin clients throughout the world. While bitcoin is a distributed network clients current connect to a central IRC channel to find initial peers. I connected an IRC client to the channel and monitored connections for a couple of days. I then ran the results through a geoip lookup tool.

The 10 countries with the most bitcoin clients are:

Position Count Country
1 2769 US, United States
2 868 DE, Germany
3 518 RU, Russian Federation
4 478 GB, United Kingdom
5 368 CA, Canada
6 332 PL, Poland
7 227 CN, China
8 227 AU, Australia
9 179 SE, Sweden
10 171 UA, Ukraine

I was slightly surprised to see that the US was so far ahead to everyone else. Also to find that Japan was so far down the list, considering the technology is said to have originated there, and that the largest bitcoin exchange is hosted there.

Notes

The irc log file contains lines which look like this:

I used the following procedure to extract the lines containing the joins and perform the geoip lookups and counts. I only used unique addresses. The GeoIP database was from MaxMind and the database was updated on the 9th of September.

grep join irc.log > bitcoin.joins
... I then lazily replaced all the ]s with @s in the file bitcoin.joins
awk 'BEGIN{FS="@";}{print $2}' bitcoin.join > bitcoin.addrs
awk '{print "geoiplookup " $0}' bitcoin.addrs | sort | uniq | sh > bitcoin.countries.1
cat bitcoin.countries.1 | awk 'BEGIN{FS=":"}{print $2}' | sort | uniq -c | sort -k 1 -n -r > bitcoin.cntcount
