at this right moment -like ever- the delta between bitfinex and btc-e is 5$ = almost 1%. Can you believe it?
And what would the actual average daily profits be after you've paid the fees and waited for the days it takes to wire the fiat from Bitfinex to you and then back to BTC-e?
I don't have any investment in bitcoin-trader.biz. Still I'm amazed at how little creativity detractors show. For example, it is easy to have revolving lines of credit for fiat. There are also multiple ways of moving fait and you can even move by using other cryto currencies. There are fees and spreads that cut into the profit, but that isn't as much an issue if you can trade a multiple of your funds in a day. It is also possible for prices between exchanges to narrow or reverse in a day.
