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?
Its not a real arbitrage since the shares cant be moved between exchanges. But in theory if you have shares where they are trading expensive relative to the other you can sell, move btc, and buy on the new exchange. You pick up risk moving the btc between exchanges as the price could come back in line
