as the title states, whats the average number of wallet addresses per bitcoin user? With the ability to trace transactions and link people together based on publically posted keys, I know many people (including myself) have generated unique addresses for nearly all transactions just to be safe. My guess is somewhere around 40-50 addresses at this point in time.. what are your guy's thoughts?
I believe they have about 150. Every service you use gives you another new address. They tend to accumulate pretty quickly. Also, all the wallets in existence generate so many new addresses. If you're using change-addresses (as you should!) you'll most likely have even more than that!!!
All this depends on usage of bitcoin. If you were to buy bitcoin once on an exchange, send the coins to a wallet on your computer, then send the coins to your "cold wallet" then you would only have 2 addresses. On the other hand if you were to buy bitcoin several times via face to face trades, and spend your bitcoin on items multiples times per day then you could potentially have several hundred (if not thousand) addresses.
