Well, actually the fees are not so much... 0,2% for transaction seems to be lower than other competitors. Anyway, this is not related with php itself; I hadn't an easy way to compare all crypto-currencies strength, with a single glance.
I've a very own version that capture my actual quantities thru BTC-e API, and create another table multiplying the rates by the quantity, obtaining all my assets in every currency in a single table...
Because I've spent some hour to realize that, I thought that it could be useful for someone else.

Ciao,
Claudio.
