This was discussed here on PokerStrategy a few times.
For example this thread:
Different currency tables
Also I'm positive that I originally learned about it from 2+2 back when iPoker introduced their currency feature. It's nothing new and iPoker doesn't even lie about it.
Furthermore it's pretty clear that the website article was written by someone who knows nothing about currency or currency markets. It takes very little math and very little effort to realize that they are rounding the currency for each transaction and it takes even less effort to realize that they always round in their favor.
Finally, as a very mediocre poker player I can tell you from experience that those tables are quite profitable. Maybe iPoker shouldn't be rewarded for such poor business practices but by using a more sensible top-up amount than 1 cents the fishiness of these games more than makes up for both the currency exchange and the excessive rake they charge at the micros.
Keith if you need to save a few pennies while playing poker trying turn down the brightness on your monitor. Drink water instead of soft drinks. Turn of the TV while you play.
Accusing a non-bank entity of rounding to the nearest cent is pretty laughable. Trying to call a company who makes their money from gambling liars? That's just plain dumb.
