BitCoin Arbitrage Opportunities

2011-09-10: Updating has ceased

The lack of spread in today's BitCoin markets allows for easy arbitrage if you trade on different markets, possibly with different currencies.

Bids and offers marked with green can be matched by someone who has the right accounts. Some bids and offers may require an account in a specific country.
