hi to all!
i have my crypto portfiolio in bunch of different altcoins on btc-e. i check my total balance a few times a day but it's a pain because all the rates keep jumping all the time. also, when i want to withdraw my coins to eur, i use bitstamp, not btc-e.
that's why i made myself a tool to calculate my altcoin value in bitcoins, then check sell rates on btc-e, mt.gox and bitstamp. basically, you just take your read-only btc-e api keys and paste them into this tool and it will sum up your portfolio in a nice page and tell you the actual worth in cash.
the tool is:
http://www.sumofcoins.comit is free and it will be developed further to include other exchanges, and many charting and analytic tools.
next added exchanges will be mt.gox and bitstamp.
cheers,
greg
