ah yes thanx man.
and hwat about arbitrage - are the payouts of the system really fast enough that i can arbitrage or not really?
also whats best way to trade E-BTC - by their site or by some program
You could do arb on btc-e. As long as your funds are only on the site (you don't have to withdraw or deposit coins), you can do lots of trades in seconds.
If you do arb over more than 1 exchange, you either have to move funds for the trade (slowing the trade down) or you have funds on both exchanges and balance later.
Since you have to consider fees, it's quite hard to do such trading manually. Some opportunities exist only for seconds or they happen in the mid of the night.
So I guess, it's only practical with a bot.
