Arbitrage, this is basically a risk free way to profit on the market imperfections through simultaneously buying and selling on different markets. Within the Bitcoin world, each exchange has a different price level, thus creating an opportunity. There are many reasons for these differences, however we are not interested in why, but how to exploit this. For more info on arbitrage refer to: http://www.investopedia.com/terms/a/arbitrage.asp
A vast majority of information online about Bitcoin arbitrage uses Mt. Gox. This is because of the significantly higher price that the exchange had a couple of weeks ago. This was due to the illiquid nature of the exchange, and the fact that it as difficult to withdraw from the exchange.
Now, Mt. Gox has various problems I am sure you are aware of, many people think that the arbitrage opportunity has disappeared however they are WRONG!
Recently I have averaged around a 2% daily return (after accounting for all fees). It is important to note that this is also compounded interest and it really adds up!
I hope that Mt. Gox doesn't stop you taking advantage of the imperfections within the Bitcoin exchanges. If you are interested in learning more please visit my blog: http://easybitcoinarbitrage.blogspot.co.uk/2014/02/bitcoin-arbitrage.html
Or send me any questions I am happy to help!!!
Interesting.
So, let me get this straight.
You just conveniently "found" a wonderful arbitrage opportunity, at the same time as Gox is allegedly having a transaction problem with fake transaction id's.
And now you want us all to be in on it? Out of the goodness of your heart?
Really?
Or is it because you need more transaction ID spoofing support, so that you can fuck over the blockchain, at some later date, and make off with all the BTC you (or other people), duplicated from Gox's wallet, and retire to your recently discount purchased Greek island?
Coincidence perhaps?
Please do correct me if I left out any details.
