Calculating Bitcoin Arbitrage Profit

I can't really agree with your findings. I still think the largest hindrance to taking advantage of the arbitrage is the international wire transfer fees that coincide with transferring money into the exchanges.

Mt. Gox - Astro-based deposits. Not available for US customers. Kraken (US Based Exchange) - Still waiting on getting their licenses on a PER state basis, until then digital currency can be bought or sold. CampBX (US Based Exchange) - ACH withdrawal only after Dwolla dropped support, only other options are personal checks (requires KYC verification)and money orders which require 4 days for completion. Their volume is much too low for taking advantage of arbitrage.

Coinbase is by far the easiest yet their trades take 4 days to complete if you have a tier 1 account. On top of that they take 1% for every buy and sell of Bitcoin and do not allow you to keep funds within the coin base platform hence no ability to swap funds easily.

I've tried arbitrage but the structure is not there to take advantage of...yet.
