Hi, I've not been an active poster at 2+2 mainly posting at FTR and Crushonlineholdem where the main story is being hosted but think that this information is important for all iPoker players to know about.
The information came to light as I was unlikely to get much playing time over the summer and decided to try and grow a minute residual bankroll at VCpoker in the time i did have available just for fun and in a way to force some discipline into my play. Having played a fair few hands , I noticed there was a big difference between my actual bankroll , and my winnings reported by Holdem manager which were also similar for my pokertableratings graph.
The whole story is documented at http://www.crushonlineholdem.com/keith showing the evidence of what I discovered, but it boils down to the fact that if you have an account with an Ipoker room, every time that you play a table in a different currency to your account currency,every single transaction will involve currency charges with rounding taking a small slice of your bankroll each time.This is not only when buying in to a table and leaving a table which has a minor effect, the major effect occurs at the micro tables when auto top up replaces blinds and topping up small amounts. Here the effects of rounding can have a massive effect on a players bankroll and was responsible for all my missing winnings.For me , it halved my win rate, for a breakeven or losing micro player the effects will be even larger as they will be topping up more often and therefore paying these rounding charges more often. This is despite Ipoker claiming that they make no profits from currency transactions.
If you play at iPoker's $ tables , do your bankroll a favour and play at a site that offers $ accounts . Then the only currency charge you will pay is when you deposit to the site and withdraw from it.If you are at a site which has £ as its currency you can minimize the effects of this rounding by buying in for the maximum and not using the auto top up and manually reloading when you deem it will have the least effect.
Unbelievable! Ill never again play at ipoker!
