You guys are looking at the wrong numbers and for all the wrong reasons.
Yes BTCe has a low price because traditionally getting FIAT currency in and out of BTCe is a painstaking task. They have been known to take at times almost a 30 days to process and credit SWIFT bank transfers; how long it takes for them to credit OKmoney and Money Polo, it is anyone's guess.
Read the troll box on the main page, you will find every once in a while someone complaining about how long they are waiting for their fiat credit to show up in their BTCe accounts. It takes so long, sometimes you naturally assume it is a scam.
BTCe is a the best for day trading, and also a great exchange to trade alt-coins. I use BTCe all time time and not once have I deposited or withdrawn anything other that bitcoins from the exchange.
All of you guys thinking of profit from arbitrage - ie buying BTC for a low price on BTCe and then selling it for a higher price keep these factors in mind. If you want to buy bitcoins with the "low" price on BTCe you are in for a considerable wait. And when it comes to coins, time =
