The two exchange system offers a nice arbitrage opportunity. I've increased my holdings by 20% historically through just a few arbitrage trades. Be careful of WeExchange, thoughthey don't pay the minimum transaction fee on withdrawals and they require 6 confirmations on deposits.
How do you arbitrage btw exchanges?
You buy stock at exchange A and then sell is at exchange B?
But how to transfer the stock from A to B?
I assume he is buying low on BTCT and selling high, then transferring bitcoin to Bitfunder when its lower and buying there
