Hi, Jonte!
Tnx for your feedback.

From our experiences so far, you can expect up to 2% of profit per month (of course it depends from the market situation).
Are we talking profit in BTC or USD? Or can you choose what type of arbitrage you want to use?
Profit is always in USD. You can decide between manual arbitrage (you set trade conditions - % of captured price differences between exchanges and
the volume of traded BTC) or fully automated (fully automated trading, as addition you just follow notifications to optimize your profit).
Hope I have answered your question.
