hey why don't you measure the volume in dollars instead of fucking coins, i can afford $100, doesn't matter if thats 70 coins or 7 coins.

I've measured all the volumes. In assumption the bitcoin society is growing exponetially in number of users, it is sufficient to observe average daily volume in BTC: if it remains const, society will die, on time interval, roughly the same, as time interval of rate ($/BTC) growing.
Because BTC volume is const for 2 months, april & may 2011, if we suppose, number of users is growing according number of bitcoin client downloads, or according rate ($/BTC) growing, society should be dead already. We observe - No. => number of users is NOT growing exponetially, as fast, as number of downloads, or rate ($/BTC), or mining difficulty (all these have roughly the same parameter t0 in exp (t/t0)).
The entire picture is obvious: there are some 1000-10000 total bitcoin users world-wide including all miners, exchange players, sellers & buyers, and the are some 100000-300000 newbies who just 'play the fool' with bitcoins.
Newbies DO just 'play the fool', because if they will start seriously, bitcoin society will die almost immediately.
