So you want to deposit some fiat into btc-e?
Thinking to bankwire - be prepared for 15+ wait time, fees and KYC. Contrary to popular belief, you can't move fiat in without being KYC'd to btc-e and partner banks. The cost (for USD): 0.5%, but min $20.
2.The cheapest instant method would be e-wallets. The cheapest options are MoneyPolo and OkPay (1% fee). But to get your precious fiat you will incur 2.1 4.5%+~$1 fee for Debit card to MoneyPolo deposit. Or 0.5% +$20 min. fee for bank wire.
2.2 0.5% receiving fee + whatever fee you'll pay for depositing your usd from your bank/card.
Thus we have at least 4% deposit fees to get into btc-e alone. And remember, you WON'T be able to a move anything before getting slapped by KYC & AML from Okpay and MoneyPolo. Still believe that btc-e is a money-laundering heaven?
But let's abstract ourselves from fiat-to-ewallet shenanigans and attempt to do what every arbitrage wannabe would want to do: exploit the juice price difference.
Huobi has an option of okpay usd withdrawal. It costs 0.5%. To receive the money to your wallet it will cost 0.5%. That's 1% already. To deposit okpay to btc-e you incur another 1%. That's 2%. Now you want to buy those cheap btc. And you get 0.25% fee for the order, because it's a market order for you need btc fast. Thus 2.25%. For the sake of experiment, let's disregard the miner fees needed to send bitcoin back to huobi. To sell your 1 btc you have to pay another 0.2%. Thus all full circle will consume at least 2.45% in fees. At this moment the highest btc-e ask is at $985, huobi bid at $1013. That is 2.84% difference. Subtract 2.45% and get ~0.4% of potential profit, provided that the market does not move against you, while you move money between exchanges.
For the "ex Soviet mob" believers out there: due to socio-economical reasons, most transactions in the countries are done in cash. Subsequently, there's a class of all sorts of people, who engage into forex exchange manually, and now in bitcoin. Many of those use btc-e as a vault and a reference point. But we too are slapped with fees that vary according to the spread installed by those exchangers.
It might seem that btc-e is a cheap place, while in fact it isn't. And as in many poor countries, sometimes it is even more expensive than your average western bitcoin exchange.
