Here’s a chart you may or may not find of interest (but we did, hence the post). A distribution of bitcoins by address, as compiled by BitcoinRichList.com.
According to a chart, about 95.46 percent of in-use addresses hold 0.001 BTC or less (as of block 280,000). That means that if any of your bitcoin addresses hold between 0.01 and 0.1 BTC, you’re in the 1 percent of the ‘richest’ bitcoin addresses. With higher balances come lower percentages, but it’s interesting to see the distribution of the 12+ million bitcoins out in circulation at the moment. It’s also important to remember that most users don’t keep their funds all in one address, and will divide them among several or more addresses.
At the very top of the chain comes a measly 2 bitcoin addresses above 100k BTC that hold 111,114.6 BTC and 144,341.5 BTC (the richest). Incidentally, the richest bitcoin address is in care of the United States Federal Bureau of Investigation — bitcoins seized from the Silk Road shut down in 2013.
