A new currency mediator

[bitmaker]

As you all now USD is now the most used currency in international business. The question is that can bitcoin or altcoins replace the USD? Can they be an end to USD mediation?

Large, persistent deviations between pairs of identical assets are unusual in exchanges and, when they have occurred (as for so-called Siamese-twin stocks), they typically have not constituted profitable arbitrage opportunities. For bitcoin, an arbitrageur could, in theory, safely profit by buying bitcoin on BTC-E and then selling it or going short (by first borrowing bitcoin and then selling it) on either Bitstamp or Bitfinex. In reality, however, this trade would entail both transaction costs and/or risk .
