Congratulations on meeting my needs of a portfolio with automatic data entry. The Cryptsy copy/paste and API import methods worked flawlessly! This is the most user-friendly portfolio that I've found so far! Keep it coming, I'll definitely be donating. Although, I would be willing to pay a small subscription in cryptocoins to keep the site functioning smoothly, just so you know.

Also, I would love to see these features implemented, and would be willing to contribute!

Import Deposits and Withdrawals;
Export all data;
Profit/Loss for each transaction;
LIFO and FIFO purchase rates;
A single graph of each coin value in BTC or USD over time;
MyAltCoin.com API.

Keep up the good work!
